Welcome to /diy/, a place to:Post and discuss /diy/ projects, ask questions regarding /diy/ topics and exchange ideas and techniques.Please keep in mind:- This is a SFW board. No fleshlights or other sex toys.- No weapons. That goes to /k/ - Weapons. The workmanship and techniques involved in creating objects which could be used as weapons or the portion of a weapons project that involves them (e.g., forging steel for a blade, machining for gunsmithing, what epoxy can I use to fix my bow) may be discussed in /diy/, but discussing weapon-specific techniques/designs or the actual use of weapons is disallowed. Things such as fixed blade knives or axes are considered tools, things such as swords, guns or explosives are considered weapons.- No drugs or drug paraphernalia (See Global Rule 1). If you want to discuss something that could involve such things (e.g., carving a tobacco pipe from wood) that's fine, but make sure it's /diy/ related and doesn't involve drugs or it will result in deletion/ban.Helpful links:https://sites.google.com/site/diyelmo/http://www.engineeringtoolbox.com/
Some friendly suggestions for posting:- First ask Google, then ask /diy/. Your question will probably be better received if you do so.- List available resources (tools, materials, budget, time, etc.)- Try to use pictures and explain the goal, if possible- Be patient, this is a slow board; your thread will be around for days.- Share your results! /diy/ loves to see problems solved and projects completed!
Hello, all.I'm a teacher at a college and like to keep busy in the summer. I am not very handy, so I think it'd be very good for me to work a job where I learn some practical skills.I probably sound stupid, but this is all very new to me. I think I would really enjoy woodworking, for example, but I have no clue what entry level position I could feasibly get. I also like the outdoors.The only /diy/ skill I have is ax restoration, which I've always loved doing. Maybe there's something with that?Thank you for all and any help. Sorry if this is off topic or unbearably cringe and bluepilled.
>>1556895Finish carpentry might be up your alley, too.
look up if there is a makerspace in your area, you wont get paid but they have all sorts of things you can learn there. Like auto mechanics, welding, woodworking, hell even arcade restoration, depends on the makerspace
>>1556895>>1556897Thanks a lot, anon. I will look into these.
>>1556897Do you think there's anything doing for axe stuff? Silly question, I realize, but I guess I can't help but ask, since the investment/payoff would be so great if I could find a way to swing it... >>1556900I guess if I can't find a paying gig, I can try to get a little experience at a makerspace. Thanks for the tip, anon.
>>1556900Totally agree. Makerspace is a fantastic idea. Learned so much from the folks in the local makerspace
didn't see one thought Id start oneRecently started with really basic Mead made from Honey (local obviously didnt pay shit for three jars of the stuff) water basic wine yeast and some dried cherries for taste. its pretty nice after half a year bottled and i have some more bottled for future tasting, any recommendations?
>>1558541Basically you're doing >>1534549 ?
>>1544176Home brewed root beer is less than .5% abv, give it a shot.
>>1558553Pretty much, but with a few small differences here and there.>>1535097>The containers need sanitizationEven if it isn't completely sterile, it's likely that the added yeast will outcompete any other organisms present. I used to sanitize my bottles with bleach which I then rinsed out with water but nowadays I just use very hot water instead. I've made over 50 bottles of wine and cider so far and none of them have become infected. I'm not saying that it's impossible, but the risk of infection is a bit overblown in my opinion.>There's no airlock or at least a pin-pricked balloonThat would be helpful, but the CO2 produced by the yeast will form a natural barrier over the fermenting juice anyway. CO2 is heavier than air, so unless disturbed, it will accumulate and prevent oxygen from outside getting in. That being said, I would still use an airlock/balloon just to be on the safe side.>There's no racking, and no aging mentioned eitherThe picture says to wait 2 months. Usually my experience is that the alcohol percentage plateaus after about 2 weeks when brewed in a warm environment, but the liquid is still cloudy with suspended yeast particles which will negatively affect the taste. The yeast will continue to settle down to the bottom leaving the rest of the liquid clearer over time. In my experience, 2 months is usually enough time to produce a fairly clear drink.The longer you wait, the better it tastes but I know most people probably won't want to wait months to drink their brew. That being said, I've drunk cider that was 2 weeks old and cider that was 8 months old and I was surprised at how well the 8 month old cider tasted. All of the yeast had settled to the bottom with very little disturbance occurring while pouring and the resulting drink was crystal-clear. If you have the time and patience for it, then it pays to wait a few more weeks/months for a nicer-tasting drink.Comment too long. Click here to view the full text.
>>1558596>Otherwise you more than likely will end up with vinegar or bitter waterUnlikely. It will ferment. It will probably get to about 13-15% ABV. Taste-wise, it will probably be OK, but nothing to write home about.Anyway, it looks like the picture is intended for an audience that isn't familiar with homebrewing or cider making. It's certainly simplified, but not incorrect. Could the technique be improved? Of course. But it's not a troll.
>>1558596>>1558598Forgot to mention that if you must drink it after only a couple of weeks, then it's a good idea to put the bottle in the fridge beforehand to make the yeast settle faster and then (optionally) strain it through a pantyhose. It will still taste a bit yeasty and it won't be perfectly clear, but it's much better than drinking it as-is.

>>1557901Maybe YOU can't weld steel to iron but rest assured, there are plenty of us that can.
>>1558575>Also. Pumping concrete up the side of a tower is a pain in the ass. You need superplasticisers to deal with the flow and fuckhueg pumps up the building.another point - high RC seems to be safer for workers than high steel. You need to lift up less heavy stuff up so less chances of workers getting hit by a steel beam etc.
>>1558583The only way someone would weld steel to iron is if they fucked something up and had to botch the fuck out of it.Sounds like you've done something dangerous that could result in brittle failure of a structure.If you've done this, tell someone before the weld cracks and someone dies. Anonymous report if you have to.Not even joking.
>>1558595Oh, you mean on a structure. Never mind.
>>1558583no you cant, you think you can, you have probably even done it, but you cant. There is no recognized method or filler material for this, brazing is however approved.
Hi dudes haven't seen a thread dedicated to these kind of questions so here we goI'm looking for a cordless screwdriver for my old man.I'm looking for something that is similar to the Bosch go but with a trigger and not pressure triggered.I've seen the "Black & Decker BDCS40BI" witch you can twist the handle so it looks like a regular screwdriver but as far as I learned B&D is not really that reliable.Do you have any suggestions?
>>1558214Meant OP... he posted the same question in another thread.Is bretty cool that it runs off straight 18650s instead of an overpriced pack with two cells that costs 10x what it should.
>>1558231>bretty coolthis has to end. bretty gud. bretty cool. stop it now. or i will bite your arm off
>>1558243At least you can’t bite off my nipple because that thing is long gone. Thirsty bitches I tell ya.
>>1558207just get some hex drive drill bits then.

I have boxes and boxes full of seashells from my grandmother passing what do i do with them? would people actually buy them or take them?
>>1557533Honestly this. Ebay. You could sell them for a few bucks a piece probably. Maybe learn how to sterilize them for the crab.
>>1557527Use them to make lime for some cement. Use the cement to securely seal your grandmother's grave to prevent her from rising and taking vengeance for destroying her precious shells.
>>1557527They are worthless, give them to me, I will pay for shipping. jk, anon, but esty is your best bet, even damaged shells can make decent money if you are crafty. Sea shell Christmas ornaments make a huge profit if you are a half decent wood worker, there are a bunch of youtube videos on it.

My wife sells handmade dolls. I'm looking to speed up her process - there is always demand for orders, she is always behind. I want to purchase a die for the outer shape ( Approx 5x5 in ). How long is the turn around time on a single down/up stamp? I could add more cut outs to the die, but it increases price.Material is thick felt - too thick for many of the existing "cricut" style cutters - and I'd have to pay more for one of their people to make the die. I'm assuming I couldn't double or triple up the felt to get several with one cut...What kind of press should I get? 1/3 ton punch press or something? Is this just a stupid fucking idea?
If you use a press, don't go hydraulic for this application. A 2 ton arbor press will have plenty of power, and move quickly enough that your wife won't get frustrated with it.
Have you considered having a stencil waterjet cut then use a guided bit on a handrouter following the shape. Sandwich multiple felt high and thighten with countersunk bolts.
Hobbyist poorfag here. I want to build a cnc machince that is capable of milling aluminum no matter how slow. I don't really want to spend more than $300. I already have a router that Id use initially and a 3d printer to help get parts. Is this really a feasible goal and has anyone looked at builds using 3d printers. Im looking at 3 of them>https://www.instructables.com/id/Modular-DIY-CNC-Machine/>https://www.thingiverse.com/thing:3004773>https://www.thingiverse.com/thing:724999Or should I just buy a CNC 3018 for $250.
You can mill alumimium just with your router if you wanted to. If you really want to build a shitty frame please don't use aluminium rails and 3d prints. Steel is way cheaper and much much better. Cold rold is also a lot straighter. Use the biggest motors you can find as you will actually need some force for milling metal and not just to move the axis. The cheapest trapezoidal screw with anti backlash nut will be better than stretching micro belts. And again 3d printed parts is the worst you can do. Zero stiffness and expensive. The 3d printed parts in the picture can be done from steel with very basic tools, you could get the material for free from some scrap bin if you ask around and the stiffness would be 1000-10000 times higher. Anyway 300$ is a very tight budget. I would say not possible but as you already have a router it is somewhat possible.
>>15584353d printed parts cost pennies. In the last link they even managed to cut steel on a printer thats mostly 3d printed.https://youtu.be/1CX3qui0-Yo
>>1558399I've been in your shoes and tried to build a cheap CNC for aluminium machining without knowing anything about machining. I'd strongly advise against it, it was a money pit and the only upside to the project was that I learned why lots and lots of things don't work.If you decide to do it anyway, at least don't use 3D printed plastic, especially not for the frame. Note how the absolute retard who designed the CNC in your picture used 3D printed brackets to hold the (way, way stronger) aluminium extrusion together on the corners. The corners are already laying over each other, you'd get a better joint just by bolting them together, let alone using a 3030 L-extrusion (which is also ridiculously fast and easy to make compared to printing big parts).Anyway, some pointers:>spend more to get better parts the first time or prepare for suffering. Supported steel rails, at least SBR12. 12mm ballscrews for every axis, give them proper mounting with ball bearings and thrust bearings, else they'll be flying all over the place and you'll get shit accuracy>all metal frame, everything you can possibly make or buy out of metal, make it metal>use thick aluminium or steel parts everywhere for rigidity>3030/8020 alu extrusions are okay for the frame, easy to work with>you need to blow the chips away, you need a compressor blowing air into the working area, if you don't do this, the chips will weld and fuck up your part, even if you use coolant, which you'll want to use (for starters it's good enough to focus on other parts of the CNC, and just manually blow chips away during work, but make sure to do it)>going slow is not actually an option, your cutting speed needs to be high to get a good quality cut without welding; the way you cut back on load for a not very rigid CNC is by cutting thinner layers, think 0.2mm depth per pass>you can control the RPM of a router by connecting it through a dimmer, but you lose significant amounts of torque
>>1558435Agree with this post entirely.The only reason kits ship with aluminium is because of implications of weight.You could do this from square box section table legs.
I recently bought this mp3 player from amazon, it's 7 years old (new factory sealed) and i understand that these rechargeable batteries decline over time no matter what happens to them.It's going to be a gift within +- 2 years from now so i have to store it a bit longer, and put some contents on it in between.What is the most effective way of preserving the batteries lifespan and efficiency? is it charging it once fully? or not touching it unless truly necessary?advice please!! thankyou so much
>>1558523They say you’re supoosed to store them around 80% of total charge, charging to 100% isn’t the best for the batteries. So charge it up most of the way and leave it be. If you really want to, check it every 6mos and make sure it’s not at 0% because letting them fall below that can kill em. Li-Ions seem to hold their charge forever though, maybe drop like 10% over a year or two. Don’t overthink it.
>>1558526Actually around 50% for lithium batteries
>>1558557so what is 80% for then?\and how critical is the difference??

>>1558498>>1558499>>1558522That's real fucking dumb. You have the X-axis motor and Extruder motors having to coordinate their relative speeds for them to not constantly fight each other.

>>1558539I tried raising it slowly all the way to 220 but it didn't seem to change much.I did however just notice that whenever the printer retracts the entire bowden tube shifts back and forth (the part where it screws into the extruder). I have some old E3D bowden fittings so I'll try replacing the stock ones with these ultra-sturdy ones and maybe that will help.
>>1558509How doe it work?
Just bought a used fan and spent a few hours cleaning it up to the point it almost looks new -- would like to swap the current switch (seems to be a standard lightswitch, possibly put in by previous owner) with something allow for different speeds, but don't know much about what would be compatible with this motor (Marathon Model 5kcp35knb057as)If someone could point me to a switch to buy and give a few hints on the wiring I'd appreciate it.

Does anyone make a guide on the frequency that things should be cleaned? You know, for the home? Like how often sheets should be changed? How often the bathroom should be scrubbed?My mother was bipolar and would beat us for chores randomly. I never really received good feedback on if I did enough or did it right. Now that I'm living on my own I'm curious to know what normal is.

>>1558371>Since top sheets are heaps cheaper and more durable than duvet covers, it's not a great choice unless a top sheet would cook you.I just find them a pain, they're very constricting and annoying. It might be another European thing with our well insulated houses, it's preferable to be able to easily stick out a foot sometimes to regulate temps. The duvets last absolute ages, like years and years, most people buy Egyptian cotton covers with a high thread count. Doesn't break the bank.Some older people still do it with a sheet, and I've seen it at shitty b&b's and hotels before. Some traditional nice places do it too.>>1558402>not even knowing how to use the three shells>expecting opinion to not be discarded
