>/sqtddtot/ - Stupid questions that don't deserve their own thread

My question:
Is there anything I need to know before casting a concrete walkway? Picture not related.
I am gonna get a bunch of Quikcrete, hopefully for less than $20 in total, to make a walkway that is one inch thick, 12 inches wide, and around 40 feet long. This area is muddy and I want to paint this strip with a yellow double line and white edge lines like it's a little road because I'm autistic like that. Is there a material better than concrete for this, or anything cheaper?

I also want to cast an arched footbridge. I'll probably form the mold with foam boards and keep it supported with sticks or something on the outside during the process. Is there anything I need to know about that before doing this?
>>
>>2029545
Don't use concrete. Honestly, it's a great material in the right application, but for what you are doing, I guarantee you will hate it and regret it. Get some stones, bricks, or some pavers and take your time laying them so they are level and look nice, it will turn out FAR better.

A thin (1" is WAY too thin), narrow, and long concrete path will be lucky to last a few months without cracking all to hell. Plus if you use too much water in the mix, let it freeze, under or over finish it, don't prep the subgrade well, or 100 other things, you'll get even worse cracking/peeling/pitting. (Not to mention you'd have to prepare it in a dozen or more pours, which would end up looking and performing poorly).

I think a footbridge like you mentioned is actually doable though. I'd recommend using wood for the form, or even just filling the area underneath the foam or whatever with dirt until you finish the concrete work. And plan on making it pretty thick, at least 4", but 6" is probably better, regardless of how small the span seems like it would be.

I'll probably use 12" square patio pavers with Quikcrete in the gaps between the pavers and in the angles of the curves. The bridge is a bullshit project because there's already two cement blocks as a bridge across the little stream with no problems.
Would it be better to use cement and put the path on a sand bedding or bare soil and quikcrete for the jointing?
>>
>>2029589
I'd probably just stick with laying the pavers on a bed of sand. Level the ground as best as you can, put down some plastic to prevent grass and weeds growing underneath, put down some gravel and tamp it down, then throw an inch or two of sand on top, and lay your pavers on the top of that.

Once the pavers are in place, just use sand between them, not concrete. The concrete would crack pretty badly in that application and spall out.

There's plenty of resources on the internet that will walk you through the process, just don't get lazy or (too) cheap and it'll turn out alright. My parents learned that the hard way on a patio they tried to make. Got lazy and halfway through just gave up on the prep work and they just laid the pavers on the ground. They absolutely hate it and they aren't even close to level and they wobble around when you walk on it.

I did not want to start/kill a thread for this so: I have a bass amplifier head which rests on top of a 1x15 speaker cabinet. Unfortunately the head is a bit wider than the cab and the feet only just rest on the cab. I feel that this is too precarious and what with the vibrations that are perforce produced by the cabinet could lead to catastrophe. Any ideas on how to rectify this? I do not want to move the feet, although I could. Aesthetics isn't very important as I will probably never play out again and I don't give a shit anyway.
>>
>>2029646
Maybe you could fashion some corner brackets that the feet can slide into, and that will in turn clamp on the cab.
>>
>>2029908
This is a good idea, capturing the feet. A bit of angle could do it. Thank you.

I have this cheap generic bathroom fan with hygrometer that is supposed to turn on when it gets humid (ie when showering).

Thing is it won’t turn on during showers even when it’s foggy, but I found out as soon as I breathe into the sensor it starts to run for like an hour. It’s on the lowest setting (60% according to chinglish manual) already.

Did I mount it wrong or something?

We just did the house with USB-A plug sockets. Now USB is the new standard. Is there actually any advantage to replacing the sockets, or are USB-A to USB-C cables just as good for charging purposes?
>>
>>2030036
Update: it’s at 60% setpoint but the ambient humidity is 65%, so it should have been on all the time and now it won’t stop. So it appears it just won’t turn on unless I blow into it, could that be the motor?
>>

Why do my soldering iron tips get fouled so fast? It’s happening on 2 different brand new irons, a Lexivon butane iron and a random chinkshit 30watt electric iron. It happens even at the lowest setting on the Lexivon. I’m using flux and cleaning the tip with wire mesh. Is it possible that the cheapo solder from china doesnt have enough flux in it and that’s making the tips oxidize so fast? Thanks for reading my blogpost

My grandma's got an 05 equinox that I'm pretty sure has a blown head gasket, but I want to be sure before I take a week off work to fix it for her, does the 3400 have timing marks on the crank pulley or something to find tdc, because there really isn't room to stick a screwdriver down the spark plug holes in the back to see when the piston hits the top

>>2030288
leave solder on them at all times. wipe the tip just before you make a joint and put solder back on the tip if you're going to leave it sit for more than a minute or so, including storage while cold
also, temperature-regulated irons don't burn thru tips as quickly

First time working inside of a panel. I am trying to connect a new circuit to the third breaker from the bottom on the right.

How the hell do I move this damn thing? I need to move it about 10 metres, going into the next room and down a ~6in step. It’s an authentic Beale player piano and almost an antique (made 1923), not super valuable b/c they were mass-produced in the interwar period, but I still want to keep it and treat it reasonably well, maybe even learn to play it one day. Heavy as fuck since Beale pianos have an all iron tuning system instead of a timber tuning block (cause of something about keeping in tune in Australian climates), I reckon it’s at least 350kg. Do I need to spring for professional piano movers or can I just get a few strong mates around?

I don't know for sure it's a head gasket, I've got a leakdown tester and a compression tester I'm gonna use to find out for sure. Compression first, because i can't be bothered to drag even my portable compressor out there unless the compression tester reads funny, but I wanted to know if there was an easier way to find tdc than shoving something down the sparkplug hole, since there's not much room between the engine and the firewall for the back three cylinders.

Thanks for the intake manifold hint though, I knew it had a two piece manifold but wasn't thinking along those lines. I replaced a cracked head a few years ago and was assuming I fucked it up or something.

Bro, right up there in at the top of that water line is a water filter inside your fridge; it's probably clogged and needs to be cleaned or replaced. The caulking has nothing to do with this.

Post pics under your sink. Do you have a garbage disposal? Is it leaking water from the top portion of the sink from the diverter? Probably on the right?

I have mice in my walls. I live in a condo ( own) no idea where they are coming from so I can’t plug or deter completely. I know they are behind one wall in particular. I drilled a hole in the wall taped a box to it with baited traps. Any other method to get them out? Haven’t checked what access the have from attic. But there are none in the house. No droppings in pantry or kitchen. Everything is cleaned and just went through and threw out a lot.

It sort of looks like the stop valve on the left has water enter from that copper pipe at the bottom yeah? The water going to your dishwasher from the hot side should have it’s own separate connection. Fresh water going to your dishwasher. Once your dishwasher drains it should cycle up to a little plug on your sink basin and flow back to your garbage disposal. If you remove the little metal cap (there may be two vertical slits in it) under that there should be a plastic cap that may not be tighten as water can come out and that may be what is draining into your sink.
Sorry hope we’re understanding each other. As far as the dripping water is concerned make sure all the ratcheting fasteners are tight. If you don’t have a constant drip and it’s only when you run your dishwasher it isn’t the stop valve.

no you need to connect the drifty boy handbrake in line with the main line to the back
your setup will not work, because one brake cylinder is open and pressure will not build up

this setup is not optimal, the handbrake cylinder will leak over time because it gets pressurized from the wrong side and will break sooner or later. Disabling your braking system.
dedicated calipers are better

If it’s leaking at that dark spot in pic then that rubber hose is probably cracked at the bottom replacing the hose would be the easiest thing and making sure it is nice and snug. While it’s off make sure nothing else is damaged.

I have a solar powered irrigation setup for my lawn and garden; The pump runs at 12v & over 300w at peak (per spec). Behind this i have a pair of 12v gel batteries wired in parallel, and a pair of 100w panels wired in series with a solar charge controller.

So my question is, from a battery longevity (working lifespan/discharge cycles) standpoint would it make sense to do everything at 24v and just get a buck converter ($40) for knocking down the voltage for the pump (at say a 15% loss in efficiency)? Basically my concern is with the high current i'm running the risk of trashing my batteries. So for example with a 24v setup the draw would be ~13 amps vs ~26.

Is it normal for condensation to appear inside a mobile home when it's cold out? I feel like the answer is obvious (warm inside /cold outside). Before I put new insulation in and cover with drywall, do I need to put plastic up between the studs to keep the insulation in good shape? Fwiw I have glass mineral wool insulation with ecose technology--basically a plant based instead of formaldehyde binder). Tl;dr should I staple plastic up before putting insulation in?

nah, do the whole thing in quickcrete. years ago my friend got sick of his gravel driveway and poured himself an entire driveway one wheelbarrow of cement at a time. it's the perfect application for your road as long as you score it properly so it doesn't crack up. doing the paver/concrete mix is stupid.

Your post makes no sense. USB plugs are still the standard, the difference between USB-A and USB3 ports is data not charging.
>>
>>2035818
yes? plastic isn't going to hurt anything but your metal is only wet because it's uncovered and the cold outside is causing condensation on the aluminum. if you're rocking a propane heater it will literally make it rain in an aluminum truck cap in the cold, so if you're heating the workspace you're actually making it worse.

so theoretically once you do insulation and drywall the cold aluminum will not contact the humidity in the living space. there should also be drains or seepage gaps so any moisture will not collect but drip out.

so not necessary but do it anyway.

I'm going to be fishing four 12/3 wires and one 10/3 wire through studs and conduit runs between. The problem is I need five wires, so I can't just come off five spools. What's a good method for making sure my five sets of wires are long enough so I don't have to pull a whole run, back it out and measure. This is going through multiple rooms and around walls etc. I also need to buy the 10/3 and don't want to waste money on an entire spool.

How do you estimate how long the wires need to be?

>>
>>2036311
all of them. all of them. all of th... no, nevermind courses are bullshit.

this is a better question for /out/ or /k/ and depends wholly on how far shit has broken down. like if you have a knife you need to know how to sharpen it on cement or >>2036375 the bottom of anon's miso pot. if you DON'T have a knife you need to know how to fire harden a spear in the short term. starting a fire or hacking together a solar oven? are you building a radio from scratch or do you just need to know how to hook it up to solar power?

if you're starting at the basics how to:
1. build a fire from nothing
2. make a shelter with nothing
3. what plants are edible in your area
4. first aid
5. basic traps
would be the big ones.
>>
>>2034463
that's heavy as fuck for a base, you could get away with a decent 6p dining table without adding supports. so basically just add a top that isn't so big it tips over, longer on the ends.

you never seen a mop? it's a cleaning head attached to a long pole, like a swiffer but more dreadlocky. also if that was moved out from the wall the water would just pour out onto the floor.
>>
>>2033445
so drips and shit aside, becasuse those are separate problems (the patina down your copper says it's coming from above) the garbage disposal is probably plummed wrong. But basically the dishwasher pumps water out that black tube. It's waste water so doesn't get on your dishes as waste water, and since it's pumped it's not like it's backing up into the dishwasher. then the water goes into the food processor and should go across and out the main drain.

if it backs up in your left sink, over the food processor, then your food processor is probably full of shit and clogged. do you run it? keep it clean? you can look down it with a light and you should see what looks like the bottom of a blender, sort of a black star or something.

second thing if that cross pipe is full of shit, food etc. it's going to fill the garbage disposal then back up in that sink again.

if it's backing up in the sink without the garbage disposal then it's a clog/blockage down the line, either in the U or further. you should have the same problem if you fill the sink above the garbage disposal and release it all at once.

if you want to fuck with it without your landlord you can stick your hand in the garbage disposal and clean out the shit then run hot water and run it (after removing your hand dumdum). occasionally run it and throw orange peels in it even if you haven't been actively shoving food down it.

if that doesn't help/solve you can take apart all those white pipes by hand unscrewing the white rings. they just fit together with a little triangle shaped white gasket and the rings tighten everything. clean out your sink, put a bucket down and start unscrewing. start with the U and then take off the back bit. you can look down the wall tube and go up to remove the cross tube. clean out the years of shit and put it all back together. don't do draino because then you'll just be handling that shit.

Unless I'm mistaken, you're doing your math wrong. You're going to be pulling the same current from the batteries in both configs (assuming 100% efficiency of the buck converter). 300w /12v is 25 amps, but you aren't passing 25 amps through each battery, but 25 amps total, so 12.5 amps per battery. 300w /24v is 12.5 amps, but that current is passing through both batteries.

BTW, 300w from a 12v pump seems really high.

>>
>>2036779
>can i just wack a 9v on there
Short answer is : maybe.
Longer answer: it depends on what the circuit inside the mill is like. Is it just battery -> switch -> motor? In which case you'll be running the motor at 150% of design spec and risk burning out the motor. It might also have some power conditioning - is there also an input jack from a wall wart?

The actual solution would be a buck converter.

That's assuming the current passing through each battery is equal, which they won't be due to real world factors.

What are its pronouns?

Yes you can put wood in aluminum and burn it. You'll have two problems, air flow if the fire is in the can and how long it lasts which makes for a bad torch.

Look up campfire in a can and penny stove for some alternate paths as I'm not sure what you're trying to accomplish.
>>
>>2037200
Cut off the top of the can, cut off the bottom. Find some wood that's about as thick af the diameter of the can, between 1 and 2' long. Now slit the can up the side so it makes a C of aluminum. Light one end of the stick while holding the far end. Venture into the night with your wooden can torch being careful not to step on any of the cut up aluminum someone made.

You're actually better off with several 6v batteries wired in pairs. A small section of the RV community has been doing this for house batteries with or without solar.

>>2037232
It's the difference between starter batteries and like AGM. The amp draw of starting a vehicle is high and quick. Running appliances, a winch or electric golf cart motor is a high draw over an extended time. The biggest problem is discharging either kind too far, they get damaged below like 11v.

In my autism-fueled mind, I have but one desire. Upon getting an area of land, I would build an extremely durable shelter. It would be 1-2 rooms and have the bare basics for living. The idea would for it to be durable enough to be a nearly permanent fixture that I would never have to fiddle around with, make big repairs to, or rebuild. So that if my entire life fell apart and I ended up with nothing except for this hovel, it'd be the one thing I'd never risk losing.

I'm thinking: Concrete foundation, cinderblock walls, the cinderblock itself stabilized with rebar and filled with cement poured into it. The roof's frame would ideally be with metal beams, but could feasibly work with weather-treated timber. The roofing itself would be made of corrugated steel, probably with a rust resistant coat of white paint to reduce the amount of heat the roof absorbs (I live in a warm and sunny area).
All utilities (electric, water, cable) would be ran into the house through a porthole in the wall which then gets a specially cut panel over it to stop drafts. The idea of this is so I never need to risk the foundation with pipes/cables that go underneath it. The water pipe would run along the ground, with cable and electrical wires going along the underside of the roof. Insulation would be a series of thick rugs on the floor and walls. There would be no ceiling, except for maybe a storage loft.

What problems could arise with this, assuming I have all the correct permits and legal approvals? Again, the purpose of this is to be an absolute failsafe place to live that'll always be there for me. It's not for living cheaply, I know how expensive permits can be, so there's no need to point of the cost.

I think this is a good idea, but I think it has some aspects that would make it a secondary option assuming I had money for a new structure.

Secondly, I live in Florida so the water table is very high. I'm not sure if that would work at all, considering people don't make basements here for that reason.

I cut a wood tray with all the fractional drill bit sizes into it up to 1/4, and put my loose drills in it. For all the # size, I put in small ziploc bags with their number on it. Anything bigger is sitting in different trays for different reasons.

As for allen keys? I just have 2 parts bins, one metric, one SAE.
All my loose keys go into them.

The reality of the situation is that all the time was pretty much wasted though. When I need a drill bit, I pull from one of my drill sets. When I need an allen key, I pull from one of my sets.

The loose stuff might as well be thrown into the trash because I never have a need for them. They are loose for a reason

Hey /diy/.

I've had some funky problems with my car starting, yet it is not the battery as far as we can tell. Several different places haven't been able to pinpoint the issue. I was not able to find anything either. The latest place I have it at recommended I get the computer flashed. Both to see if that fixes the issue, but more importantly to fix the hard shifting it has when it shifts gears.

Does anyone have experience with reflashing your onboard computer, and is it worth it pay for it or try to do it myself? Would this even fix anything, or is reflashing not really necessary?

Normally the aux heat on a heat pump is a set of "heat strips" or resistance wire coils that take a lot more electricity to run than regular heatpump mode.
Your thermostat can be wired so the aux wire (not sure of the color, you can look at your thermostat manual) goes to the furnace rather than enabling the heat strips.

As for cost, MOST of the country it is cheaper to run a gas furnace than a heat pump in normal mode. It is almost always cheaper to run a gas furnace than a heat pumps auxillary heat strips. In my area, its marginally cheaper to run a heat pump than a gas furnace because I have a combination of cheap electric rates, very mild winters (heat pumps produce heat much more effectively at warmer outdoor temperatures), and the local gas company wants a 60$ monthly fee just to have a connection in addition to their gas charges (I don't have any other gas appliances, so it would cost me 700$+ a year just to have the service)

You may have scrap from the belly of the leather. This is inherently stretchy and floppy. I'm pretty certain that reddish-brown scrap front-and-center of your picture is belly, based on the organic curve on the right side. Otherwise, be aware if you have any oil- or chrome-tanned leather, which is soft no matter where on the hide it is cut from.

Belly is good for wet molding and holsters and things, but not for belts or things that shouldn't stretch.

A person a few years ago did a bunch of experiments with hardening leather. It's a long article, I believe using stearic acid or gelatin were the best performers. Doesn't really help the initial cutting though. May try a rotary cutter.

I need to bolt down a power rack. There's not enough room in the garage so I want to bolt it down in my basement. It has some thin ass cheap floring and then there's a piece of plywood eother 1/2" or 3/4. The hole is 5/8" for the base. So do I just buy 5/8" screws and put a washer and that's it? Will it be sturdy enough so that it won't wobble? Each leg has 4 holes

hey guys, i never use this board so I'm not sure what exactly belongs in this thread or not, but I'm posting here just to be safe. I have a little bit of a problem where I burned some kind of fake wood floors (not sure if its vinyl or linoleum or something else, though I think it's linoleum) and I need to know if there is a good way to patch up the hole. so far I have used wood filler, which seems to work except for the fact that the color is a bit off. is there any better solution that doesn't involve me ripping up my floor? is there some way to dye the wood filler?

If it worked before then reflashing won't change a damn thing. That's old / inexperienced mechanics that "don't understand them com-pooters" talking. define "hard starting". is it slow to turn over? that's an issue with battery / cables / starter / solenoid (or undercharged battery due to alternator). learn to diagnose properly. I won't list the steps because maybe you meant... it turns over fine but doesn't fire. that could be many, many things. again, learn to diagnose, not even knowing what kind of car it is we can check for fuel presence / pressure, and presence of spark. no fuel? pump / fuse / relay / wiring / antitheft. fuel present but low pressure? pump / filter / wiring. no spark? coil(s) / fuse / ignition module / crankshaft sensor in each case, learn to test those items, never throw parts at it.

The cheapest and easiest thing for you would be to find Low Temperature Aluminum Brazing rods.
You can buy the rods for like $10-15 in the welding isle at the hardware store or on amazon.
You also just get a cheap Propane torch set for like $20 at the hardware store

Then just braze it together with the torch. I works pretty well, ive used it to weld aluminum together a few times.

looks like water or oil. blow some air out of the compressor with a blow gun or empty paint gun. does it feel oily or just wet? if it's just water, drain the compressor tank and install a filter. if it's oily, you might have compressor issues and just need a new one. it's always good to use a filter tho.

Wood filler is supposed to match your color before you put it on, and then you stain over it.
Unless you go and find the exact right color that matches your floor (which never happens), it will never look perfect and unnoticeable.
>>
>>2039112
You need an oil and water separator in your line.
All normal air compressors will shoot out water from condensation when it compresses the air. Oiled compressors also shoot oil into the tank from blowby in the cylinder.
Thats why they sell airbrush compressors which dont have those problems.

Hey /diy/ does anyone have any tips for removing drops/blobs of hardened epoxy?

I've recently fixed a broken headstock on a super cheap guitar I broke, and overall it worked great but I was a bit lazy with the cleanup before it dried and I have some dried globs that pushed out in the direction of where the tuning pegs go.

I basically just used this video (crack was almost exactly the same)

https://www.youtube.com/watch?v=8xo_sRMirXo

I was able to remove most of the other residue with the razorblade like in the video, but these globs are harder already and also in a very curved area (pic related).

It's probably ok if they stay there but it's just kind of annoying if anyone has any ideas.

hey /diy/, sorry, I don't know where else this would go so I'm asking here

I bought these silicone mats to put food stuff and hot trays etc. on. They are fine, but they're just slightly too small for my needs.
Luckily I have 2, and I was thinking of cutting some off one, and joining it onto the other to increase the size.

How would I do this? It can't leave a gap or anything, because these are to protect the table from hot dishes from the oven. What can I use to join them that's heat resistant and safe?

Probably the default stupid question.

The water in my shower doesn't drain as good as it did once. Now I wanted to just grab a plunger and get some pressure going in that bitch but the problem is that around the drain there's small tiles (as is the whole shower floor) so the thing doesn't attach properly.

What alternatives can I use that are not heavy chemicals or anything like that.

>honestly wouldn’t bother it won’t look good or stay together well
Thank you. But the thing is, I still need a large silicone mat, This was kind of the best for my specific purpose. I don't want a thick mat, I got a relatively thin one that still manages to protect from the heat

Silicone doesn't have a melting point, it just combusts, so you can't weld the two pieces together without using an adhesive. Since the edge you're trying to bond is thin you'll need some kind of backing strip that you apply adhesive to and then place the two pieces onto. It'd probably be better to buy some liquid silicone, make a mold the size of what you want, and pour a thin layer to make a new mat that's already the size you want.
>>
>>2041553
do you know what a trivit is? there is a reason they aren't a non-porous mat.

pastry mats are like 28"x16" normal kitchen silicone is 24x16" dog feed mats are like 32"x24", and floor applications start at 56"x56". Ignoring that you don't actually need a seamless mat for what you're claiming, what size do you want when you say "large"?

It's usually hair clogging up your shower drain. There's not exactly a lot that goes down them besides that to clog them up like other drains (i.e. you're not pouring grease down them or flushing tampons down your shower drain). So you need to remove it somehow. Drain cleaner melts it. If you don't want to use drain cleaner then you can buy what's called a drain auger to snake out the drain.
>>
>>2041519
for a few bucks: get a zip strip for drains
for free: swing by any autoparts store when it's rainy or snowy. pulls some wiper blades out of the trash can out front and strip the steel out of the rubber
either option: shove down drain catch hair pull up "clot"

you shouldn't even need to modify the wiper blade metal if you go that route, just find one with a little rectangle missing near each end.

Thanks, guess the idea might have to be abandoned, sounds like a lot of faff for something a bit basic really
>>2041576
Well basically, sometimes I just want to put the oven tray straight onto the table/desk/wherever i want to eat, but I need a mat like this to do so. A trivet also works, but I also like having a drink, any cutlery, etc all on the mat.
The mat I have fits most of my oven trays, but for one of them it just barely fits, and leaves no space for me to put a drink or anything.
My current mat is 30cmx45cm or something close to that, I only need arond 6cm more each way, and the extra doesn't even really have to be heat proof now that I think about it.

But is there a way to join anything onto the silicone mat which will give me a larger surface area and not fall apart?
>>
>>2041625
>But is there a way to join anything onto the silicone mat which will give me a larger surface area and not fall apart?
not that would be worth doing. i.e. you could sew them together a la Indian moccasins but it would be hard to make the holes, prone to tearing out and make a raised ridge.

you could lay them together edge to edge and oversized staple them. the tool to reach and have effectively big staples would be more than just buying a bigger mat.

you could put one in a pillowcase end and sew around it, then put your bonus strip up against that and sew around that. probably the most durable. Ideally this would be done with a sewing machine but you lose the nothing sticks to it property.

I mean effectively anything you could try is not only going to probably not last but would be more expensive than a new mat.
>>
>>2041639
So you think the best solution would be to just buy a new mat, probably bigger than the size I want then just cut it down?

Shit, I spent a lot of time looking at these, most of the ones I looked at didn't seem suitable. Settled on these and not sure why I thought the size would be fine.
I don't even mind if I can do a messy job with this as long as it sticks together as one piece. Even sellotaping the bonus strip to the bottom of the mat would be fine for me, but I don't think the tape would last with the heat, and Im not sure it's even safe to mess around with heat, tape and food all close together like that

Well that's good
I thought maybe having it near food would be a bad idea. I know it'd be on the underside, but with the heat and everything I thought maybe it's best to avoid. But I'm pretty clueless about this stuff as you can probably tell
Aluminium and Blue tape seem like really good ideas. I just wish I could get them in more black/dark colours
Do you think just using normal sellotape, masking tape or duct tape would work or is it a bad idea? I probably have some lying around somewhere, don't have aluminium tape

you have to ground clear regardless, I both ortho ground clear and remove as much organics as possible. the black plastic stuff works for a few years but winds up breaking down and with holes. I've had better luck with the landscape fabric, even though it's meant for bushes and flower beds it doesn't seem to break down- then again I'm tearing out 10 year old mats and seeing results in the first 3 years of the new mat. also you should absolutely double up layers if you're not.
>>
>>2042090
masking tape is the best out of the 3 you listed. it's probably the best to try just to see how it works, but it will turn brittle and be hard to remove in a year if not months, and also might leave residue if you leave it on too long (again months) duct tape adhesive will melt and also leave nasty residue almost from the get-go. I hate the stuff. sellotape probably isn't going to stick very well and it's not flexible in the way you want. the properties vary widely with brand and type. the latter is true of masking tape as well. duct tape sucks no matter the brand or style.

the masking tape you have is the best option for trying without buying, an if your shit doesn't fall apart immediately you can upgrade to blue tape. also in my head you're taping it on both sides- just taping it on the bottom is going to have it fold out and pull away from the surface of the tape greatly reducing any life of the union. you kind of have to pick form or function here, and looking nice brings us back around to: just buy a bigger mat. it's the only thing that solves all your problems with this.

just curious if anyone has any advice, right now it feels like I'm selling myself short and not working towards something. I know I would be making less money as an apprentice but I can afford it.

I bought a part of a sectional at a goodwill and its got controls on it to adjust it but the plug was on another piece of the sectional. So its just got a cord to plug into another part, so I looked at the motor and its input is listed as 18-35 V 5A Max, so I was just going to strip its cord, strip a wall plug cord, and then throw a 24 V 3.7A ac-dc power block from mouser in between. Does this seem like it should work in theory?

Just butting them up. But I'm just practicing for now. The weld isn't serving any practical purpose

Need some aesthetic advice lads. I'm building some vinyl record carriers out of maple and I'd like some input on what I should line the carriers with. I was thinking some stick on velvet, but even if that's the right choice I'm not sure what color to go with. Any recommendations welcome.

Pic related, it's the outside finish of the maple. wood conditioner+dye+polycrylic.

How do I know what kind of motor do I need to rotate a 300-500mg structure at the speed of around 300-400 rpm?

Am I going to be limited by my L298N with its maximum current output of 2A?

I would love for the motor to be able to rotate the structure really quickly, including changing direction immediately and I have no idea what voltage/current/driver I need.

If you believe any other shithead could do your job. Its probs worth skilling up if you can afford it.

If I plug a light light circuit (with a switch) into a socket using a plug then there's nothing technically illegal about that, right? It's only frowned upon if you connect the wires behind the socket?
It's kinda out of sight and there's a lot of sockets so I don't mind losing one if it means the installation is both easier for me and more 'legal' (not that anyone would know anyway but it means more peace of mind).
