>>1950977Its great, give yourself at least 3 years of learning from the greybeards to get up to speed. Welding knowledge helps. It is a mix of engineering, math, coding if you cnc, and problem solving. pretty chill and you can make 150 if you are good in less than 3 yrs. https://www.youtube.com/watch?v=GsxLF-Db7ukbest part, start your own machine shop after.
I told my coworker with zero machining experience I would help him finish his 80% lower this weekend. we're going to be doing it on a bridgeport, but I wrote up a g code program so I can stand behind him and tell him step by step where to go with the dro. can anyone with a g code simulator confirm that this looks right? I did mine on a haas mini mill with dynamic toolpaths so I can't just reuse that program. not sure if .125 doc is too much or not. https://files.catbox.moe/7abt3d.txt

I had a nightmare I was trying to light my furnace, but the burning piece of paper I was jamming in there touched a wire and the wire insulation just burst into flames like a fuse and burned all the way up inside some box where more wires are as I was furiously smacking it to put it out, then a minute later I smelled more burning, pulled on some wires and plastic/rubber wire insulation was on firebare wires anons

My relief sculpt. This is just some shitty soft pine from an old cupboard door I tore out, but that's leads me to a question: What's a good wood for machining? My mill has a max spindle speed of 10600. I'm using a 1mm diameter tapered carving bit.I would do contour cutting but it ups the runtime to unreasonable levels, and if I used a wider ball mill I wouldn't get some of the creases I'm going for.Curious if anyone has any experience cutting wood, and what would be a good choice. As you can see cheap shit pine gets feathery, but I imagine I'm going to have to so a fair bit of sanding either way.

Not that surprising the the NFL swept it under the rug. They swept the fact that he stabbed a man to death, then paid a patsy to go to jail for him under the rug too.
>>1953538Yeah man, sports ball is shit, I haven't watched it with any consistency in like 7 years, and it was only because my friends watched it then.But my father in law is retiring and moving to an island so I made this for him. The NFL nor the Ravens don't get any money from it, I assure you.... Why did they try to lie about the deer antler spray shit, though? Some compound in that fucks with the results of an HGH test?
>>1953544>Why did they try to lie about the deer antler spray shit, thoughSo that the media swept it under the rug. They wanted the feel good story of old man Lewis winning the superbowl in his final season, so give him some bullshit out for why he failed the test.I dont know why I even watch, my team sucks and its not even fun especially with the empty crowds this season.

Hey guys, I've got a little 6" Atlas 10100 I got a while back for $200. Being what it is and me not being a machinist, I haven't used it much, especially with a three jaw chuck. I just found out about turning between centers and I already have a live center for the tail stock. I blacksmith enough to demonstrate a a local museum and thought a lathe dog would be fun to make with hand tools. I could forge and file the part easily enough, and tap the hole for the set screw(?) but I wanted to make sure that I'm not overlooking something that would send it flying off towards my vital bits. Does it have to be precise, or can I make one?
>>1953590>He attends to relationships because he knows how much the people he interacts with matter. “Purchasing people tend to like me. I get quotes back fast,” he says. Machine tool service people are also valuable; they visit a lot of plants. “I find connections through my connections,” he says. This is the only viable avenue he has found to finding new business.
>>1953593it needs to not be brittle
>>1953558idk try cocobolo
>>1953558It really depends on the limits of your machineSome hardwoods are pretty tough
>>1953618It shouldn't have any problems cutting any wood I wouldn't think, I might have to turn the feedrate down a tad.I got the machine for mainly making aluminum/plastic projects, but recently have just been cutting wood. I've done a few cuts on steel to test it, but that's pretty much it's limit.
>>1953596Neat. That's more than doable.

Check this out, it's a modified 3D printer that essentially works as a CNC mill. It can "drill" and machine steel.Could this be an option for poorfags or apartment cucks who want to get into machining?https://youtu.be/DINs7eMw7IQ
>>1954819No, it's a half baked, low powered EDM that barely works. Proper EDM has its uses, but it's not a replacement for standard machining tools
>>1954859ECM and EDM are very different though>it's not a replacement for standard machining toolsWhy not? If you can't use a mill, why wouldn't this be sufficient?
>>1954862>ECM and EDM are very different thoughTrue, ECM is harder to setup and even less useful than EDM is, and is rarely used in the industry in comparison.>, why wouldn't this be sufficient?What on earth has convinced you it would be "sufficient" for anything? Did you watch the same video I did? Do you know nothing about machining at all?
>>1954868>ECM is harder to setupAre you sure? I've seen super cheap ECM setups (including the one in the vid). EDM machines seem a lot more expensive and complicated. >What on earth has convinced you it would be "sufficient" for anything?I (like most people) don't have the space or money for proper lathes and mills. This setup could allow you to machine small parts. All you need is patience. So it's better than nothing imo.
>>1954873I'm not talking about physically building the device, since I in no way believe there will be anyone building a bolt on device that would hold any tolerance or work to any acceptable degree regardless. I'm talking about machine setups to actually make parts, especially if you are trying to replicate and replace a mill. EDM isn't suited for that, ECM even less so.>this setup could allow you to machine small partsHumor me, what sort of parts do you think you'll be making with these.Keep in mind people have 3d printed cnc routers that can cut aluminum and thin gauge steel
>>1954885Apparently you can cut quite complex shapes with it. But I will admit I have no experience with this technology, so I guess I will have to wait and see if it actually goes anywhere.

Theoretical dream.Imagine you could buy logs of spruce wood per solid cubic meter price of 15$ in convenient lengths locally wherever you setup your shack.You start out with only the most common tools and want to >make profit>build something>use the opportunity temporarilyWhat machines would you buy? Would you hire personel?My dream is to setup some form of compound and start an underground organisation helping people whos right of self determination have been taken away without their consent or without them commiting a crime and offering them a place to stay until they recover + a compound for people to work together until their vision of what they want to do becomes clear and profitable
god i love 4mm dia endmills, with the 1mm and 2mm trash they always loved to snap the moment they even tickled the stock, but with the 4mm they are indestructible, i frequently crash with them into fixtures and shit and they never snap, plus since they also have 4mm dia shanks i can mill down down straight walls that are longer than the flute length

This was added recently.Is Fusion 360 going full jew? Fucking hell man... i really like fusion.. but no way in hell i'm taking out a second mortgage to pay for the pro loiscence.Don't force to switch to the virgin soldworkws _;
>>1955717>he didnt leave fusion the second they announced the changes
>>1955731Abandon it for what? There is no alternative that even comes CLOSE to being as good as fusion. So what am i supposed to switch to? Solidworks? Autocad?? They are all fucking trash compared to fusion.I hope someone finds a way to create a pirate version of the fusion pro, but i doubt it because fusion is heavily tied into cloud functionality
what requires less forcereducing feedrate and increasing DOCorincreased feedrate and reducing DOC?My shitty router steppers are losing steps and i would like to solve it without slowing down the whole thing

>>1953958 If this machine is like the one i work with it looks like your R plane is set to -.5 while your Z is at -.375. It looks like your drlling maybe 1/8" deep. Should change your Z to -.125

tell me about machining chrome plated shit. is it going to fuck my tooling? will the plating chip along the edges?
>>1955733>I hope someone finds a way to create a pirate version of the fusion proYou do understand that Fusion is a babby tier cut down version of Inventor right? And that you can pirate inventor and use it offline?Also Solidworks is better than fusion in every single way.
>>1955972Oh so it is fucked up? It's supposed to be drilling 3/8 deep
>>1956285How big is your drill. You probably don't even need to run G83. Unless the hole is 3x deep as the width of your drill you can almost certainly just feed down.Q should be the depth it adds per peck. I dunno what 2200 means in this case.I dunno why your R plane is negative.
>>1956319I think it's fucked because his r plane is below his drill depth
>>1956341That's kinda what I'm getting at.It looks fucked in general. Like I said, I dunno what Q2200 would be. thousandths would still be 2 inches.I also don't know what axis C is referring to. Or what machine this is on... Anyways.
>>1956280Which one has more similar workflow to fusion 360? After all the time i invested into fusion, i don't want to just throw it away by using a software that is completely different plus is really love the concept of sketches and then extruding from them.
>>1956443You should probably just buy Fusion 360 if you are looking for rare and proprietary functions in the program like extruding from sketches.
>>1956456>buyI am not opposed to buying software if- you pay once to get lifetime access- you can install and use it without internetWith fusion you are forced to pay monthly or yearly and you can't use it fully offline, so in the case of say a global pandemic which will put a strain on the infrastructure causing it to collapse, taking internet with it you are shit out of luck. How are you going to design spiked bumpers for your hummer to plow through the infected if fusion doesn't work offline? you won't, you will be dead meat.I used the free fusion license and autodesk kept promising they care about hobbyists and won't fuck them over... and then they fucked their asses with a metal rod and taking away vital functionality and locking it away behind a paywall. If i could pirate fusion pro i would, but this is not possible so i basically have to switch to either solidworks or inventor
>>1956383>>1956341it's a bunch of 5/32" holes drilled over an inch deep into the face of a part on my lathe.the code I posted is for the carbide spot drill I run before using a parabolic flute drill to go deeper
>>1956459mastercam has CAD right?
>>1956443>Which one has more similar workflow to fusion 360?Inventor, if you can use Fusion, you can do Inventor.

Yep pretty sure my Y axis machine zero is off on live tool lathe w/ Y axis. I bet there is a parameter for that, but can I just use the G53 work shift stuff?I guess I will just have to try it.
>>1956459You could either buy Alibre workshop, which is okay for the price ($399). Or stop giving your money to the Jew and pirate your software of choice. ZW3D 2019 is pretty good, it's a very good CAD/CAM solution which is piss easy to pirate.

I’m 26 with no knowledge of the Machining trade but I’d like to learn to gunsmith. Is it too late?
>>1956868everyone wants to gunsmith, it's crap pay and hard to find work unless you're in a big cityguns related manufacturing on the other hand, like making reloading press parts and stuff, maybe your own line of barrels?
>>1956543Well your R plane should still be higher than your drilling depth I would think. Though yeah, if you're only going 3/8th in with that tool, just feed it straight in with the spot and skip pecking till you drill deeper with the flute drill.
>>1956459Extruding from sketches is in solidworks, autocad, inventor etc. Its not rare or special, its standard.Your clamoring about "workflow" because of what daily drivers say about it, but you clearly have no clue what they are actually talking about. You need to do some actual research anon.If you had done that in the first place, you would have known the AutoDesk has been locking down the free license for years now, piece by piece. Nobody but you is surprised, everyone who wasnt stupid would have told you from the beginning not to bother with it.

>>1957158I started ~3 years ago at 29 as a button pusher and was setting up jobs within like 6 months.It's easy to get started, but there will always be some shit you didn't know.I saw 65 year old men sharing tips at the place I started. A lot of "huh, i didn't think of that" stuff.
Chips in my hair
yep G53 work shift stuff fixed it, some backlash apparent though.
What's worse for a shitty diy cheapskate CNC:Timing belts or threaded rods (standard metric thread ones, not trapezoid)?I'm leaning towards rods because of the gear reduction but I heard they don't last long. Is that true?
making 100 of these little wire rope guides, why am I getting such a shitty surface finish on the boring?
>>1957598What kind of CNC machine? Kind of matters...A large-diameter threaded rod (like an M12+) will be more rigid, but slow and inefficient. The belt will allow the machine to move faster and have less backlash, but it will have more stretch than the rod.Personally, I would (and did) save for Chinese ballscrews. But, if that really wasn't an option, I'd use a good, wide belt. Despite the fact that they do stretch more than a screw does, it's not by nearly as much as you might think. If you're cheaping out that hard, the odds are very good that the frame itself is going to contribute far more to a lack of overall rigidity than the belt does. Dealing with the backlash/speed issues of a threaded rod isn't worth it, at that point.
>>1957643turns out DOM A513 tubing is actually kind of hard unless it is annealedhttps://www.practicalmachinist.com/vb/cnc-machining/turning-dom-154011/
>>1957659>What kind of CNC machine? Kind of matters...Simple router - more to experiment and tinker with than producing something actually useful. I'll be happy if it cuts wood well but I want to push it as much as I can get away with.I plan on using fairly weak Nema17 steppers I got dirt cheap, so torque is a priority over speed.Backlash seems fairly easy to reduce: preload with two nuts against a spring.So what I'm most worried about is the wear on the thread.
>>1957643I think I should have made them from solid bar stock instead of fucking with this stupid tubing.and is anyone going to care if my backside chamfer tool won't reach the veery start of the radius? it's less than like half a thou deep there.
>>1957848fucking pic didn't post
>>1957848>>1957850oh and the tolerances are all +/- 0.010"
>>1957850Just finish it with a rout-a-burr since finish doesn't seem to be an issue.
>have to face end of part with lh threads>make stub mandrel and run spindle backwards with upside down lh tool>still looks wobbly even though part was squarely on my mandrelI should have made the mandrel longer so I could put the other end in the tailstock but I was being stingy with my material. I'm not sure if there was runout because I was using the 3 jaw or if it was actually crooked because I fucked the threads a little not realizing that you have to keep the half nut on making metric threads.
>>1957876lol you're right im gonna have to ask if that finish is acceptable, it's really not so bad
>>1957643So I have figured out I can part it off most of the way then finish the back chamfer to part it off, which will leave it hanging on my ID grooving tool and not require a part catcher. might get a video of this sometime.
>>1958058You'll still be left with a small point instead of the radius though.Also that sounds like it's going to fuck up your boring bar insert, but aight.
>>1958090inserts and bar came with the machine, not very impressed.
I still don't know how to part off without leaving a burr on every piece
>>1958103you should try a handed insert, they make R and L handed parting inserts which cut slightly deeper at one side, like say you want the burr to be left on the stock piece instead of the part, you use that specific handed parting insert
>>1958112I tried stuff like putting the tool at a slight angle or grinding an andle into a hss parting blade but it still leaves that sliver that tears off.
>>1957852No, if they bitch about that then they're going to bitch about anything.
>>1958100>not very impressedDunno what you mean by this.I did just realize that you could cut that radius with a grooving tool though instead. Then part off. You'll have a burr on the flat back off the part, but you can just rub it on some sand paper to make it flat. Which you can do while the machine makes the next part.>>1958103Not sure how you could. The piece is always going to part off with a little extra material on it.
>>195764311/100got the program pretty much ironed out I think>>1958337>>not very impressed>Dunno what you mean by this.The fucking insert keeps coming loose, it's just a screw-down type not a clamp over the top type. This shitty DOM A513 tubing is actually super hard from the stresses imparted by drawing. It's not hardenable, but it's work-hardenable apparently.
>>1955733Fusion360 is shit. You have to be a masochist to put yourself through its garbage workflow on the regular.
Is there a pastebin or something for newfags like myself? I'm mostly interested in working small aluminum and wax blocks, is one of those gay little benchtop models all I need?
>>1957643a kennametal top notch grooving holder and various inserts were also included with the machine, I've been using it to groove and profile the relieved section in the middle. When profiling (moving left/right in the groove) it hits like 35% spindle load at the corner, on a 30hp spindle.I think because the inserts don't have a chipbreaker or relief angle it's just like ripping the shitty steel off there. Doesn't break a chip just long strings.
>>1958448>cloudshitWhy would anyone trust that shit with their time and work? One server crash in a datacenter somewhere and poof goes everything.
got email from guy with machine, they say they can't even load a program over RS232 onto it because they don't have the option from Mazak for itso it's like a 20+ year old machine with probably very little wear on it as it's been hand-programmed with mazatrol the whole time.

Sweet, got the OK on the surface finish.
>>1958553you do realize they have multiple backups and in addition to that you can store all your files also locallynot to mention that fusion is becoming industry standard
>>1958553It's generally stored with some redundancy so it would have to be a pretty huge failure to bite you. That being said; fuck the cloud, fuck SaaS, and fuck these greedy-ass software companies.t. cloud software dev
>>1959308SaaS allows them to actually keep code proprietary though, and is likely the reason Fusion is so comparatively cheap.For instance the code they use to convert files from another format into fusion files, requires uploading to their server and downloading the result.What are the chances they are using a hacked piece of code from the competitor's software to do the conversion?

Fusion kept wanting to make it two ops regardless of what the constraints and offsets were set to. So I switched to hsmworks and it worked fine.
>>1959312I think that's a possibility, but I'm sure they gain more value just from forcing consumers to pay over and over again than they do from obfuscating some stolen file conversion routines.>>1959352Many programmers consider themselves self-taught, but classes certainly help. I learned a whole hell of a lot from this series: https://www.youtube.com/playlist?list=PLB63C06FAF154F047The cloud certs from amazon help get a decent position, they're highly valued at some places. I have an unrelated liberal arts degree, but got into the field by programming for myself for a few years until a contracting company was willing to vouch for me and find me a position. There are contracting companies that will go so far as to falsify work experience for you, if you're really desperate.
>>1959360Fusion is autodesk, dssault is SW and Catia. It's a tier thing. Like how powermill is autodesk's premium CAM
>>1959368wish I had powermill :/ and a good 5-axis
>>1959367What languages do you see becoming highly sought after? I know C#, SQL, Python, and C++ in that order.
>>1959370Interesting question, I'm the guy making wire rope guides in his garage right now, not the software guy.I know C++, C, and C# in that order.
>>1959369>tfw wish i was rich so i could buy a tormach mills and top tier CAD and CAM software>tfw if i was rich i wouldn't waste my time with machining and instead go fuck hot college girls on tropical islands
>>1959387businesses have better ROI than real estate in most places, and real estate has a better ROI than the stock market, plus it lets you invest in an asset worth 10x the money you put into it via a mortgage.So either start a business or buy some rental properties?
>>1950977First time on this board does AvE browse here?

why is a boring bar $70 and an endmill $35
>>1959480More demand for endmills so the price will be slightly lower.
Anyone ever used a Yasnac i80 control?
>>1959396How the fuck would we know. You should ask him.
>>1958419>The fucking insert keeps coming loosesounds like the threads are fucked up or something. try putting a lockwasher on it lol
>>1959634im a little under halfway done, the screw finally gave out and I replaced it, it still comes loose every 3-4 parts. somewhat annoying
>>1959396He's a fucking hack. This board routinely shits on him so I dont see why he would hang out here.He's also not a machinist, why would you ask in this thread?
>>1959452Why isn't that edge broken? Looks sharp bro. Prog a 45 maybe?
>>1959689>He's a fucking hack.He's wrong about a lot of shit, but he's admitted before he's pretty much just learning on camera.He's half a machinist, anyway.He once tried peck drilling with a friction drill, and it - of course - fucking exploded. That was fun to watch.
>>1959695I did, but I didn't notice the turning insert had the tip broken off.I just kept thinking it was deflection or some shit. Still don't know how the whole tip of my turning insert broke off on that shitty tubing.A513 T5 really is some gnarly shit to work with, won't break a chip for shit.

apparently mark serbu shows off some firearms machining on his channelhttps://www.youtube.com/user/markserbu/videosapparently he makes .50bmg rifleshttps://serbu.com/
I know this is not exactly Machining, but someone here might be able to help.I need to find some sort of software that could align and compare two sketches (or two dxf-s,...) and also measure deviation.I have measurements of a gear (dots) and cad drawing of the gear (solid lines).And I want to find out the deviation between those two. But before that, they need to be aligned together, in a best fit scenario- where deviations are the smallest. What software should I use?For example this is what I want, but I need it in 2D, not 3D (0:10 to 0:45):https://www.youtube.com/watch?v=7gPt-ZV2c-k
>>1959723>but he's admitted before he's pretty much just learning on cameraHe didn't need to tell anyone that.Why you would bother watching someone beg for patreon money while "learning on camera" is beyond me.His fake shop talk got old 5 years ago. Waste of time when there are so many other worthwhile channels to watch.
If you were to finance a new 5-axis mill, what brand would you go for?
>>1960054mazak if price wasn't a problem, haas is I needed a budget machine that could pay itself off in a few years.
>>1959993upwork and $25 ?
>>1959993I think inkscape can open dxf files, and has a measurement tool. You'd have to draw the ruler lines manually, but should work. I think.Blender might even be able to.
>>1960093Maybe as a last resort.>>1960127I can open dxf in Fusion 360 and Solidworks. But I need some software that would align those two sketches as perfectly as possible, so that measurement of deviation is as accurate as possible.Alternatively I am looking for software that would automatically connect 5000 dots (it is the whole gear, not just the tooth, as on the pic) to their closest neighbouring dots, so I can make extrude of that sketch and send it to someone with geomagic control x. I would prefer not to connect all those point manually.
>tfw need 42hp spindle for a 6 tooth pulley groove
>>1960137>perfectly as possible, so that measurement of deviation is as accurate as possible.I'd say they are aligned when the deviation is minimal. Can't you write a script for one of those programs that does this?2 objects, align them closely by hand, check difference to each closest point between the 2 objects, compute the difference, nudge slightly, compute again, check if total difference is reduced, etc.
>>1960194>I'd say they are aligned when the deviation is minimal.Yes.>Can't you write a script for one of those programs that does this?I do not know how to or even if that is possible for solidworks or Fusion 360. I agree with your concept, but I have no programming skills to achieve that. I was hoping some machinist here is using something like that to check on finished parts. Maybe something for coordinate measuring machines?
>>1960190Why so much?
>>1960620for all i know that insert is like 3 inches wide form tool
>>1953473>relief sculpt>layer linesShiggy diggy
>>1960743You won't be able to see them so we'll when I'm done. Gonna sand it a bit. Gotta buy a slightly wider carving bit at some point.But I had some tiny areas to get into with this so I figured I'd start small.P sure I'd get better results overall if I cut against the grain instead of with it as well, to prevent some of the feathering that's happening.
>>1950977Not machining, but a metalworking question: what's the best way to fix this dent without removing the wheel and beating on the inside of the fender? I was thinking I might drill a hole in the middle and try to pull on it with a bolt or something.
anyone here have experience with machining 316L stainless. yes I know what I am asking 316L stainless is not usually machined its laser cut, but i need to make a few small parts on my CNC router out of 18Ga 316L sheet and just destroyed 2 of my nicer carbide end mills cutting 2-5mm Holes in about 2mm thick 316L sheet.and when i mean destroyed i mean i reduced 4 flute 1/16th or ~1.5mm carbide end mills to tooth picks. they were mid range end mills so I was lucky they made it that far. Any Ideas on tooling that would hold up or have replaceable tips? between 1-2mm? I know i am going ot eat though tooling but at this point i am looking at $50 in tooling per part.....
>>1953558Try maple or ash. Maybe white oak or pecan depending on what's available in your area. Avoid red oak. But remember that you'll always be needing sanding after CNCing wood. That's just the nature of working with a fibrous material.
>>1960929The crease is too damaged for that to workBut if you want to try, look up Slide Hammers
>>1960964Thanks, any brand or /diy/ recommendations? My main goal is to cover the hole in the fender and mount the missing side marker lamp. I've got a sheet of aluminum set aside for the job, but I figure I should try to get the fender into close to the right shape before I rivet or zip tie that into place. I'm not trying to make it look super pretty, I just want it to pass inspection in Pennsylvania.
>>1960983>hole in the fender*hole in the bumper
>>1960939More flutes means weaker flutes. But if you're turning them into toothpicks you're probably feeding too fast.
>>1961044>More flutes means weaker flutes.eh?

>>1950977fellas you ever just try to re time half finished threads and end up fucking it up and ruining your thread profile?yeah.... me neither haha
>>1962941at least the kennametal top notch threading tool would fuck up those threads good
>>1962941I have a cross threaded part I need to fix but I'm still not sure how I want to try doing it. it's an externally threaded nut that spins on a shaft. it conveniently has threaded holes through it so I think I can put a set screw in one to lock it to the shaft and then put that between centers. then I can pick up the thread and try to clean it up. I don't know if I want to do it under power or just put it in neutral and turn the spindle by hand.
will uncoated 3 flute carbide have problems with cutting pcbs? (fr4)I don't really want to buy those special corn cob endmills etc if i don't have to.I'm just wondering if the fiberglass will damage the carbide.
>>1963195donnow tool life might not be as good
how do these jews stay in business?I literally just ordered the exactly same 10 pack from chinks for $4
>>1963568sometimes the difference in carbide is so obvious that when you pick up an endmill you are like "woah this is heavy" compared to the others
>>1963578maritool brand solid carbide boring bars are slightly heavier than micro100 bbs
>>1961339guess I should unstick my parts catcher sometime.brass job is on the queue, might as well use it for that.
I was trying to drill a 1/2" hole in some brass today but as soon as the drill flutes touched the stock they grabbed and started twisting the stock in the chuck. it looked like they were trying to gouge into the stock instead of cutting. I pre drilled at 5/16 before I ran the bigger drill and that worked fine. I tried different spindle speeds and it happened every time unless I fed in at like .001 ipr. was it just the feed rate fucking up? this has never happened before.
>>1963878either clamp it down or put a stop to stop it rotating.the pre-drill hole probably made the bigger drill want to thread it's self into the hole (pulling it down further)
>>1963878>twisting the stock in the chuckthat should not happen, at all, from a drill if it's held in a lathe chuck. I thought you were talking about a drill press.
>>1963881it spun in the jaws and marred the fuck out of the stock. I tried to back the drill out in the tailstock but it just pulled the entire drill chuck out of the tailstock morse taper. it looked like when the material grabs when you break though, only at the start somehow.
can you guys recommend a small/mini lathe that can handle both wood and metal (aluminum) for a beginner. I would start out doing some small woodturning protects like for pens, and then make aluminum body pens. Something small, that would be less that 12" I suppose. For a beginner. So don't tell me one that sells for $2k. But I don't want a total piece of shit like the $60 crap sold direct from China, or even a Harbor Freight junk. A couple hundred bucks or so.
>>1964088Buy a wood lathe, and then buy a metal lathe.They are completely different.
>>1964096Great answer, retard
>>1964088>So don't tell me one that sells for $2kThis is the wrong hobby for you anon>>1964175It actually was a great answer. Its not his fault you are getting filtered by your budget.
I'm kind of glad I'm not this guy working on clapped out machinery all the time.https://www.youtube.com/watch?v=sPdDw3dR9ak
>>1963878If you're using a hss drill you could grind a negative rake onto the flutes, that was always the trick on a lathe with Morse taper tools in the tailstock.
>>1964088A couple hundred bucks - so, something worse than "harbor freight junk"? I think proxxon has some "micro" wood lathe that is "good enough" for wood pens, and you *can* turn aluminum pen bodies with certain wood lathe tools.
>>1961526I can't imagine operating a lathe while wearing a scarf.Lucky fuck.
>>1962604Were you the one making those chunky cable rollers?How much did you make from that job?
>>1961526how do you get that old and be that dumb? not wearing anything that can catch was day 1 of trade school for me.
>>1965023I imagine it probably just slipped his mind. Most accidents in general are caused when people are too comfortable.
>>1965019Not nearly enough, but I gained a new customer, and I used some old reground inserts that were included with the machine so tooling cost was negligible.I spent most of the time fucking with that shitty V insert boring bar because the insert kept coming loose. I'm definitely going to be using the parts catcher to catch parts and the subspindle to pull the bar going forward. No one wants to be a glorified robot.
>>1965095perfect low paying job to pay the heat bill though, tolerances and finish are basically an afterthought because they are going to be molded into rubber afterward anyway+ / - 0.010" on everything, radius included
>>1965095pic related is the only bar puller I have experience with, but it works quite well (dunham bar puller).if you do that, plus your parts catcher, and use a grooving insert instead of your V insert you should be able to have the thing pretty much just automated, and get a proper radius on the inside. cut up with the groover and down with the part off tool and the only thing you'll need to do is sand a tiny ring on the back (as you can see professionally illustrated in the pic)But that's just what I'd do. There's a million ways to machine a cat.
>>1965611I spent all morning getting the sub-spindle all set up for bar pulling for the next job.

>>1966333You machinists sure are a contentious bunch.
>>1966464so are welders, engineers, and pretty much anyone who has a job and thinks they do more work than someone else.
Im a manual machinist/toolmaker apprentice running a bridgeport with a prototrak to make one off parts. Today my boss handed me a print for a part he needed and accidentally way overdid the tolerances to plus or minus .0002 on the largest parallel surfaces on the part. So the 1in dimension was .9998 to 1.0002 acceptable tolerances. It was just a 1inx2inx4in block with 2 holes drilled through it. We laughed cause it was overkill and the journey man toolmaker jokingly said "if you want us to nail that for you, we can but it'll take a little longer" that got me thinking, I'm not certain I could hit that tolerance on aluminum. How would you do this? If it was tool steel I'd do it on the surface grinder but it's not. My plan would be tram head in to dead nuts, obsessively clean every bit of the table, indicate vise to dead nuts, fly it, oversize by a thou and mic the part all over marking high and low spots and bring it in by hand with a large extremely fine file. Hand finishing is the only way I think I could do this and it would take me all fucking day? How would you guys make this hypothetical part?
>>1966613grind it like you said. or machine it slightly oversized and hit it with a lapping compound and super fine grit sandpaper.
>>1966613>on aluminumI did some button pushing for airplane parts and the tightest tolerance we did was .0005On the lathe we made some stainless steel bushings that were .0002That doesn't answer your question, but aluminum is pretty dependent on temperature, so you'd have to do a lot of dialing in.
>>1966648>tightest tolerance we did was .0005On aluminum I mean.
>>1960773Something harder won't feather (/as badly, as long as you go slow and your bit is good). You can experiment on oak stair treads for something cheap to play with. Lots of shapeoko/x-carve guys were taking laminate floor samples from stores to carve coasters. All-plastic flooring is fun to play with, but lots of swarf to clean.
>>1966613you can buy grinding wheels for aluminum, donnow how they work probably require coolant.also I would just "lap" it on a piece of sandpaper to final dimension.
>>1966653I tried maple and it feathered worse, but I don't think it was as dry either. If I went against the grain I imagine it would do better too.I have a bird in the hand with this pine one, so I think I'm going to stick with that rather than experiment with other wood for this project. I'll remember it for the future though.Next material I mill will be plastic I think.I have some 80% lowers I think I'll try to engrave images on for kicks too. Dunnon what yet. Pepe or something.
>>1966648oh yeah that's a good point, al will change like crazy with temperature. probably have to let it normalize to room temp before taking a measurement lol.
Sweet, got paid already from new customer. Currently finally getting around to the brass parts order. Halfway done atm.
>>1966685deburr that shit. you could cut open chestnuts with that.
>>1966746customer wants to do that himself, he has a whole crew of guys doing finishing stuff on the parts. vibratory tumbler, media blast, hand polishing, etc.they do a lot of metal spinning too which is cool.
>>1966685oh yeah, got my part catcher unstuck too.but uh, it holds the little box out way too far from the chuck to be useful, I assume there is a way to adjust it, because if not then I have to grab the part with the sub-spindle then move the sub up to the part catcher and pop it into the part catcher.which just seems silly.
>>1966782>care is taken to not overheat the barrel by taking breaks in between cutswhy don't the fucker try breaking a fucking chip, no wonder the shit is heating up.
>>1966262tempted to buy one since I chipped my 1/2" endmill years ago and never replaced it. if I'm doing all manual work now am I better off with square corners or the .03 radius?
>>1966785square corner for sure.
