Does anyone know a site that sells open ended PCIe 1x connectors in pic related? (The black connector)
Looking for the bare slot not on any PCB. I can only find closed PCIe slots on the usual Digikey, Mouser, Newark.
Need the connector open ended to physically but not electrically accommodate a longer card. I get I could cut down a closed ended one but I would prefer to just get the right part.

>>1043542
If I remember PCIe slots correctly, you can simply cut the plastic slot 'open' to accommodate a PCI x4, x8, x16 card.

Your card should automaticall work at x1 speeds, and all of the power pins are in the "key" that are the same size.

I recently bought a cheap chinese soldering kit on eBay, but instead of flux-core solder it came with this. How do I use this? I would google but I have no idea what it's actually called.

What the fuck is a carberator and how should I go about taking it apart and cleaning it? I try to read about then and they talk about diaphrams and needles, shims, bowls and shit.

I'm concerned its full of tiny bullshit parts and it won't work when I go to put it together.

How to diy a projector.

Im unartistic as fuck but i want to make a yard silloette. I.e. a 3/4 shit of plywood, cut into a gorilla shape, and painted black.

I have a descent sized foundry and will be making a plaque to accompany it.

Also have a 50watt solar panel and large deep cycle batteries.
I will be installing said lawn ornament on public property near my small towns lake and attempt to make it look proffessional and as if someone that was supossed to be cementing memes in the ground actually did it. Tasteful nightime lighting and a bronze plaque that simply says Never forget and the dates. I may purchase a seperate panel and light to light up the small memorial already out there just as more "camolage"


The problem i have is tracing a photo off the internet and making it on a 4x8 sheet of plywood to cut out.

As a thank u i will be posting a build thread after i am done.

I actually am done dicking around to the point im hooking up a 60s model volkswagon motor and 200 gallon propane tank on a traler. Got everything but an air pump that can handle 40 horsepower... anyone have any thoughts on where to sorce or how to build the pump? Will post build thread here if u do. I wanna run 4 1" impacts and still not run out of air.

Lol, poor bastard. U can buy flux and paint it on. Lowes sells it near the pvc and propane torches and shit. Flux core is cheaper tho.

Good luck

If have money get good solder gun from radioshack soon. It has a larger tip than the rest.

Lol, can help some. Not a lot though. If small shot like a mower, should be a small screw or bold on the bottom of the little round the that looks like a bowl (the bowl) take it off being careful if there is a gasket, clean it out with a cleaner made for carbuerators and chokes (carb and choke cleaner) and there is also a bolt hanging down the bowl was covering. Take that coxksucker out and clean it. There should be a fucking microscopic hole in it. Clean that fucker out and reasemble.

If its in your car do what i do for my big block chevy. Soray half a can of cleaner in the carb. Throttle the fuck out of it a few times (be careful of backfire in your face and/or neckbeard, change the shitty olastic fuel filter, and then if it doesnt work, give it the finger and cry to your dad or another mechanic.

>>1043567
The only reason why I don't want to cut the slot is this is on a product I'm looking to possibly sell and not on a usual computer motherboard. But I realize this may be my only alternative, can't find 1x open ended slots from the factory at all. I'm starting to wonder if these Chinese manufactures are just cutting the slot themselves using a CNC or something because the actual part seems to be unobtanium.

>>1043609
Are you a plumber? Rosin core is for electrical. Acid flux (what you generally find in the plumbing section) is the last thing you want for electrical. Also, right tool for the job; variable watt station for fine electrical, gun for construction work.

>>1043692
You could build a little jig for your dremel to cut the slots perfectly each time
Making something kinda like a mini table saw where you slide the pcie onto the blade would be easiest

>>1043603
It could be rosin. Is it hard and brittle?

>>1043692
Its seriously cheap plastic, and if you take your time with an xacto blade, nobody will notice your modification.

Alternatively if you're fine with spending up to $10, buy a pcie1x riser ribbon cable. Its like an extention cord for the 1x slot. You can modify the cable and the motherboard is unchanged.

I want to make dry ice at home, but don't want to pay 1000 bucks for a maker plus the price of canned co2. Is there any sort of cost effective way or equipment to just freeze regular air solid at home in small amounts? Don't say fire extinguishers either.

>>1043907
>freeze regular air solid at home in small amounts
Despite what the hippies say, air doesn't contian enough CO2 to so freezing it solid = dry ice

>Don't say fire extinguishers either
It's pretty much the only way without paying big buck for some serious cryogenic equipment

I heard that some supermarkets sell dry ice for keeping food cold but have never actually seen it being sold anywhere. This is probably the cheapest way to get dry ice. Check if your local store has some in stock and if not you're fucked and better get to work buying some fire extinguishers.

>>1043913
They don't stock it because the dry ice sublimates so quickly; their inventory would literally evaporate. Give any ice retailer a few weeks notice and they can usually order it in for you.

>>1043913
>>1043915
I've gotten it from grocery stores before but where I live now there are none that do. They always had a big flat freezer they kept a bunch in.
I know there isn't a whole lot of co2 in the air, I just wanted to freeze the whole amalgam or as much of it as I could, wouldn't i just need to be able to pressurize it enough for it to liquify/solidify enough to put it in a mold or something?

Some walmarts sell dry ice?

>>1043922
Technically enough pressure + cooling to get CO2 solid would make CO2 slowly separate out. But that takes literally forever because the air contains so little of it. Even though the CO2 wants to settle and form a solid, all the other air molecules and atoms "carry" the singular CO2 molecules to a point where absolutely nothing will happen to the cooled air.

TLDR; This won't work.

>>1043935
>>1043922

I like to over complicate things so I looked into the problems you'd face if you worked around the settling out problem. Meaning, the actual setup required.

First, I checked how much air you would have to work over. 17 kg yield about 1 kg, which seems reasonable to me.

Next, the actual conditions required:
considering you probably don't have a way to make actual dry ice temperatures, I will assume you can get freezer temps, which are around -18°C. Given this, I got the CO2 phase diagram and checked the pressure required to get it into solid form at that temp (pic related)
Aaaaand where already over 1000 Bar. Which basically means it's impossible. 1000 Bar tanks are possible and exist, but are really really expensive. I'm pretty sure they aren't sold for non-industrial or scientific use and you will never ever find one to fit in your freezer. Not even mentioning the kind of compressor needed for this.
TLDR; just get some fire extinguishers.

Stick your new boots in a clothes dryer and tumble. No heat, just air.

>>1043976
These guys are giving dumb advice. Put them on your feet and lace them so they are skin-tight, with just room for your toes to wiggle. Wear them like that. They won't be comfortable at first but they will break in and be perfect in a few days and you will not get blisters or need shit like moleskin because no part of your foot will move inside the boot. Getting them soaking wet and walking around speeds up the process.

Most people fuck this up, break them in and wear them too loose and they get blisters like retards.

The baffle plate that sits in the top of my fire has broken, it was fire bricks with a steel plate behind it, being a tight ass I was thinking about getting a 20mm plate of steel from work and use that instead, yes I know it will warp and won't last as long, but are there any other negative reasons? Fire has a wetback in it also, if it is massively detrimental to the fire I won't do it, but I'd like to know if anyone has done this..?

It's an AT style (DIN-5) connector. You can get passive AT->PS/2 adaptors, or an active AT->USB adaptor.

But that keyboard is filthy as all fuck, and unless you know that is has a nice switch type, is worth less than the adaptor will cost.

Or be like every other normal homeowner and get an attractive light fixture/sconce.

If a device is rated for a certain wattage, can it be run with different voltage?

For example can a 12dcv 60 watt automotive headlamp run off 120acv with 0.5 amps? Seems like less amps would be less likely to catch fire.

>>1044347
No, carefully pull one key off. Carefully, because some kinds have a loose spring under the key, and it can pop out in a random direction. Then take a pick of what's under the key.

Just type on it. If you like the way it feels, buy the adapter.
If it works OK with the adapter, clean up the exterior and use it.
Putting a keyboard back together can be a daunting experience if you haven't done it before.

>>1044399
For example a lamp is usually a purely resistive load, we use equation v=i*r.
Lamp has a resistance, (which increases with temperature), to find the current divide voltage by resistance it becomes clear that by increasing the voltage actually more current flows.
This is pretty much why things have set voltages, you can't give them any old voltage because they don't self regulate.

Some electronic equipment has built in smps (clever power supply) that CAN work at various voltages but not any and all voltages so be careful.

>>1044399
What device? I mean just in your example, usually things that take AC input won't accept DC and vice versa.

I've replaced both of the switches (left and right click for the clueless) on my deathadder now, and if I tighten the screws directly under the LMB/RMB to a point where I'd call it tight, it ruines the click action, like it's all sandwiched together too tight.

The switches are the exact same mfr/dimensions with some slightly different specs that I didn't choose them for, just bought the cheapest japanese omrons.

For a while I had only one switch replaced and it did this on the replaced side while the stock side was able to be tightened properly.

Any ideas what I might have done wrong, or were the screws just not meant to be tightened all the way?

If the radiator is metal, take it out and get the crack brazed or soldered. Some radiators have a resin composite tank at the top and if this is cracked, get a replacement.

Sketchbooks are like $8. In no reality is it cheaper to make a book of blank sheets of paper than buy one.

You could buy blank reams of paper and use them unbinded for slight savings. You could buy a hole puncher for another $8 and a $2 binder and fill it, but buying blank paper and binding it into a book will necessarily cost you more than just the $8 cost of a normal sketchbook.

If you want to get fancy and design your own book cover and learn to bind books, that's a different matter, and it's not cheaper than buying a normal sketchbook.

always use separate flux for any decent electrical soldering.
the flux core is insufficient for proper soldering, but can be used just fine for anything tin plated.

how strong a flux you use depends on the metals involved and the project, as >>1043756
said, acid flux is normally not used on electrical projects because the ionic residue fucks your shit. its also impossible to clean

>>1043662

well that shit looks to be solved, but I'll leave this here since I already typed it out:

If they wanted to make a book with specialty papers that don't always come in sketchbook or block form (like certain types of watercolour paper, printmaking paper used for drawing purposes, etc). It can be cost effective depending on the paper sheets themselves (or if they have that shit already). The types of binding chosen would decide the final prices (yarn & threading vs 100% pvc glues). To keep it cheaper, spare cardboard from cereal or soda boxes could be used as a base over something like chipboard for example.

There are several YT videos from the user "SeaLemon" regarding book making & binding techniques. Aside from her, I'm just gonna link to one that deals with WC paper from a different user:
https://www.youtube.com/watch?v=3187ovmPINU
If you don't wanna bind with threads, there's always shit like this:
https://www.youtube.com/watch?v=E0HZZv9ArTM
https://www.youtube.com/watch?v=S-4iTvvX2sw

If OP just wants to paint on the sketchbook cover, then get some craft acrylics from a craft/hobby store like Michaels or AC Moore. Could use the sales coupons they usually have each week to put towards it if you wanna be an especially cheap fuck. On their own craft acrylics are usually one dollar per tube, but could be lucky to see if there's larger amounts of student grade acrylics on sale. Especially helpful to get your base colour/colour that you're gonna 'prime' your covers (white, black, etc) in a larger format since it'll run out faster than the other colours.

Or just glue some patterned cardstock (usually also on sale depending on store, three sheets for one dollar) on the covers and be done with it.

>>1045314
Half Price Books.
I picked up 5 NEW books with recommended prices on the back of $20 or more for just $4-8 each last week.

Be careful on their websites, though. It's like $5 shipping per seller, so if you buy 3 books from 3 different places they might end up charging $15 in shipping, negating a lot of the savings. But if you buy from all the same seller you should be fine.

And often, the extra $5 wouldn't matter anyhow. $5 for a book + $5 for shipping is still often cheaper than $20 for the book on amazon or similar sites.

Is too difficult to glue wood together and get an even finish?

Just a heads up, you run boards the long way. Don't copy that design. It's one of the basic rules of furniture making that you always prefer a few long boards over many short ones.

>>1045474
>Is too difficult to glue wood together and get an even finish?
Not at all. The trick is that you glue them up, let it set and then finish the surface. And by finish I mean planing or sanding it, not stain and such.

>>1045486
I want to apply epoxy resin to finish it. But thinking more, probably will be a good idea too to build the countertop with separated pieces.

I have a window unit AC, it's not a permanent install. The side panels (pic related, but not exactly, it's a googled image) have a tendency to rattle in the bracket.

I've tried stuffing bits of waste plastic in there, but it doesn't stop it, the rattle just moves to wherever isn't stuffed.

Are there any better ways to go about this, or do I just need to get a shit ton of something I can wad up and get to it?

Get some plywood, mount the plywood to the AC using some tec-screws (self-tapping) and brackets. Make sure theres nothing on the inside of the AC that you'll screw through and damage. Those steel cases usually come off with just a few screws.

You can also get a little foam rubber weather stripping and mount that around the wood and AC were it contacts with the window. Style points: paint the wood so it doesn't look trailer.

Yo /diy/

I'm laying flooring in my attic. Was previously just joists covered with insulation, above a non-load bearing plasterboard ceiling.

I've partially put flooring down in the middle of the room and now want to extend right out to the masonry of the walls. However the way I laid the planks means there's no more space on the lefthand joist to put a plank, and there's no joist immediately next to the wall.

Would pic related work if I drilled metal brackets into the joist and the wall and used these plus a central joist to take the load? Distance between the joists is about 2 feet and the maximum load would be about 100kg (my fat arse). If so what kind of screws and brackets to use and how close should I space them?

>>1045790
You can just use a 2x4 nailed into whatever 2x material your joists are, no need to futz with screws and brackets like that. Should be quicker, probably cheaper, especially if you already have the materials on hand.

>>1045815
OK, thanks. What about the wall side though? Attach a 2x4 "rail" screwed in with plastic plugs?

I want to cast some things with silicone, no fancy shapes.
First I will have to make a mold of the original but alginate and silicone are quite expensive therefore can I use something else to make the mold instead?
Only the end product has to be silicone.

>>1045960
>alginate and silicone are quite expensive

alginate is inexpensive

you're going to have to buy silicone to make the cast item
it's unlikely you be able to buy the exact amount of product for your casting
use some of the same product to make the mold

>>1045968
alginate is 17€/kg same for the silicone. Imo thats quite expensive.

The mold should have around 2-4 liters volume, that would be 0,4-0,8kg of alginate (Water:alginate 5:1) or a shit ton of silicone. I'm not to thrilled to pay a lot of money for molds cant use over and over or even more for just a mold.

Imagine though that I'm too poor/lazy to use any tools other than a drill.

I will be smelting aluminum for the first time next weekend and am confused as to what flux I should add to purify the scrap aluminum.

Will anyone shed light on this for me?

>>1046061
when I watch kieth rucker do it, he adds just regular table salt, then scrapes the aluminum oxide off the top.

I have a 20A circuit with a bunch of 15A duplex outlets on it (totally legal and very common)

On one of these outlets I can plug a 6A vacuum and a 12A electric wok. (18A total)

The breaker won't trip because I'm not pulling 20A, but the outlet is only rated for 15A.

Can I burn my house down doing this?

>>1046115
>Can I burn my house down doing this?

You can burn your house down playing with matches.

If you're worried it's wrong, stop doing it.

>>1045972
If you're looking into alginate, I have to assume you're talking about body casting... you don't use the body cast as your main mold anyway (the process naturally destroys the mold no matter what you're using). Alginate or plaster bandages are really the only things you can use; silicone products cure overnight. Suck it up and buy the alginate, Europoor.

>>1046115
I would upgrade that outlet if you are going to e doing this

>>1046115
20 Amp outlets cost like $4 and take maybe 10 minutes to replace if you have 2 left hands and they are both all thumbs. If it's a concern, replace it.

If you like it, just look for a PS/2 to USB adapter. Just be sure to get an active one, not a passive one. Passive ones were for the weird devices that were on the bubble between PS/2 and USB, and are just wires. You need a chip to decode the PS/2 interrupts and convert them to USB polls. Something like https://www.amazon.com/Monoprice-Keyboard-Converter-Adapter-110934/dp/B00IACID2C/
Since it's the old AT format, you'll need something like https://www.amazon.com/Belkin-Keyboard-Converter-Adapter-Din5f/dp/B000067RBR/

What is a good cheap mold release for molten aluminum and uncoated steel? Baby powder?

>>1043608
Buy 10 2/3 cylinder pumps that each require 4hp to run
That should be good for like 120cfm @90 psi aka infinite air
But for real you won't see peak HP at idle or low load so you should Google or get it dynoed at the rpm and load you plan on running at and if need be you can use a restrictor or smaller carb to force a lower power output if needed
Or just have it drive 40hp worth of 240v power generators to power 240v motors for the pumps if you're willing to accept the power conversion loss (only 20% of combustion turns into mechanical energy, minus engine friction loss, minus +/- 90% alternator effectcy minus belt loss minus power transmission through wire loss)

>>1047116
The vids of Kieth Rucker casting aluminum, bronze, and steel use baby powder, talc, and a releasing powder which is the same as baby powder. The trick is to apply it properly.

So here's the thing..

Someone bought me a shower cabin and had it installed here.

For reasons I don't know, it has a telephone cable (rj11) attached to it and some sort of a phone? mode without a function to dial or do anything other then activate

I've attached a extender cable to it and tested the wires to see if I'd get a response in my multi meter, but there is none.

what is this all about? could I just wire a 3.5 mm jack to the end of it? will it just listen to the current conversation if wired to the phone plug?

How do you clean a wooden deck like pic related? That white residue is from a few weeks ago, when I put my catbox outside and it overflowed during a thunderstorm. The litter was a special clumping kind, so I'm assuming this is the glue mixture that was on the litter itself. I live in an apartment complex, but I don't want to have the maintenance guy come out here if I don't have to. Someone said it would be as easy as scrubbing it with vinegar and baking soda, and others are saying "bleach". I live above someone (i think? ive never seen them before but i hear them), so anything I put out there can't leak down onto their deck.

Should I just call the maintenance guy?

I have this modem here. I received it on 2008 from my phone company, used it until this year, when it could not work and was replaced by a new one. Its capacitors, taiwanese electrolictic ones from the Ronyo brand, leaked due to usage. I already was told on /diy/ that it's easy to fix, just replacing them. And that I should, because it's good to have a spare one IF I need.

So, I checked the (physical 2008) manual, and it says:
>ADSL interface * supports G.dmt full rate: speeds up to 8Mbps downstream/640Kbps upstream
This worries me a little bit. I currently have 5Mbps connection, and the next connection I will have will be, probably, 10Mbps. I don't know when this will be, but probably no more than 5 years from now. So, I suppose this modem would not be good anymore and I would need to donate it to someone living outside the city centre (where I live), because it's supported speed would be lower than what I would have.

If your backpack is old, be aware that the strips that support it on your back could be near rupture. I used my backpack for 4 years, then paid a dressmaker to change the tires.

I'm trying to fix an old mechanical keyboard that has keys that randomly start and stop working on it. All the keys that weren't functioning properly are fixed by filling a small crack in the PCB with solder, but one key, the Z key still doesn't work, and the keyboard doesn't type "Z" even if I short circuit the solder joints of the key.
Is it possiblethat this small scratch is the cause of this, and if there's anything I can do to test and fix it.

Hey /diy/nosaurs. I have a neon sign that is acting up. It was flicking on and off rhythmically about .5 seconds on, .5 seconds off.

I really don't know, I put the keyboard in storage for a year or so. It was working fine when I put it there, but when I took it out to use it with an old PC I acquired, I noticed that random keys in the lower left hand corner stopped working. The keyboard was in rough but working condition when I got it, so it's a possibility that it was damaged before I even got it, since I didn't have it apart before this.

I've read. The image OP posted on that thread is wrong, its one to plug a PS/2 male on a DIN-5 female. What I need is the reverse, a DIN-5 male on a PS/2 female.

I can just use just a DIN-5->PS/2 adaptor and forget about USB, but, as there is some kind of BERG connector inside the keyboard, wouldn't be better to replace the entire cable altogether?

>>1048099
>The image OP posted on that thread is wrong
Yes, but down a bit others explain how they successfully accomplished what you asked about:
Keyboard -to Passive AT-PS/2 adapter -to Good PS/2-USB adapter -to Computer

>replace the entire cable
If you have one available, it would make a 'neater' adaptation.
The protocol is compatible but the pinout on the berg connectors (could) be different.
Make sure the PS/2 pins go to the correct pin on the keyboard berg and you'd negate the need for one adapter.

I'm interested in this because I'm still considering getting out my Tandy keyboard.

If you think the tracks are broken (scratched through) just scrape the coating next to each side of the break and put a drop of solder as a bridge across the break.

Because it would cost me a lot of money to make loads of keys to break into your house.
It would cost me nothing to try 5-10 maybe more combinations every day I walk past your house and then when I got it right after 2 years of trying (or once if I watched just watched you type it in) and burgled your house there would be no evidence of forced entry and your insurance wouldn't pay out

I have a socket like this and a plug like this. Are these made to work with each other?

The plug is on my welder and the socket is on the generator im thinking about buying. They dont make generators with the exact same socket.

There is no carpentry general and I have a question. I live in a apartment and have no tools, no hacker space available, no muneys, barely enough energy and nothing to do anything. An anon suggested I got into woodcarving and I think that is a good idea because I can get some good wood that falls of trees in my university. But I'd need a knife. What kind of knife should I look for?

>>1048921
Yes, but you should check to see if the generator's power output to see if it works with your welder. A plug mismatch is a trivial problem and only exists as an attempt of idiot-proofing.

That dead wood falling off trees is going to be 'great' for carving.

It is not dead. Heavy winds, and being loaded with bromeliads filled with water makes healthy wood fall. Are you angry? Who rustled you jumbos anon?

Not sure if I posted this before, my grand mothers 50s ranch house is having some major efflorescence issues in the basement.
The house is about 5' concrete wall until earth level then 2' brick coursing to the the first floor. Along two sides of the house (under chimney stack, and under concrete steps) is major mortal crumbling, with minor cases all along the rest of the basement.

Does this involve re pointing outside mortar as well as inside? Is this a job best left to pros? She also has a crack in the concrete foundation wall that leaks during heavy rains

Then it does work. The varistor should work as protection for over voltage.

Ok this is getting confusing.

I have a welder that will do 140 amps on 240v. The welder recommends a 6500 watt generator for 240v.

The generator I was thinking about buying will trip if it goes over 30 amps. The math says that a 8000 watt generator will do 33 amps on a 240v.

Why would my welder recommend a 6500 watt generator then?

How does one know go about matching stain color when you don't know what the original was?

I have a desk that's (according to the website) made of acacia wood and colored "ash grey." I'd like a put together a monitor stand, but I don't want to color to be so far off that it looks stupid.

Ideally, I wouldn't have to buy every stain/wood combo imaginable to trial and error it.

>>1048183
>>1048185
There was this one crack that was on a relatively large track that I just removed the coating on and placed a bit of solder on. This fixed all of the broken keys except for the "z" key. I ended up following the traces that were attached to the z key's switch to see where they lead to, and I did a continuity test on from the lead on the switch to some solder joints on the track, and I found out that only one of them seemed to have been damaged.

I did some experimenting with a wire to find out what point on corresponded to the z key, and then I soldered in a wire to bridge the points.

It's not necessarily a clean fix, but it will do.

>>1049150

Good for you. Glad you got it going.

>>1049133
Take a removable part of the desk (drawer?) and a piece of the wood you intend to use for the stand to a paint store. (Sherwin Williams?)
They match stains as well as paint and do it daily.
They'll even test their recommended stain on your board to verify how it's going to look.

>>1048996
Great. But how are you sure it works? It's 12 years old. It could not work anymore!

I'd like to gouge out a hole in a hardwood rifle stock to fit my own rifle. Will a dremel be able to handle it? The wood is beech if that matters.

>>1049529
The dremel will probably work. If you're just reaming out an existing hole to a different size, you'll need a reamer which will not fit in the dremel.

What you should do is get an appropriate size drill bit, make the hole, then insert a collet (use brass, steel will rot the wood) to act as a tunnel for the action's retaining screw.

>>1049529
What hole are you talking about? An action screw hole? If so anon has it right, but I've never heard of steel rotting wood.

>>1049548
>>1049544
It's more like a slot. I want to widen and deepen it in order to fit the receiver better.

Are harbor freight vises any good?

They have a 25% off coupon for labor day.

>>1049548
Well the problem comes with steel oxidizing (rust) and speeding up the rate at which the wood rots, even if its been treated and oiled. Its why some of the nicer rifles of yesteryear and even modern wood implements (knives mostly) use a brass plate between the steel and the wood. Brass, while it oxidizes does not rust and hold in the moisture to rot the wood. An easy example of this is many old rifles used brass butt plates instead of steel. However in the past, brass was more expensive than steel, hence why many just didn't do it. Nowadays, brass is more expensive and wood is rarely used.

>>1049560
So you want to widen the receiver area of the stock to drop in the action?

>>1049563
Yes, exactly. I want to widen the receiver slot to drop the action in.

>>1049564
Yeah I mean you can fuck it up and hack it out until the action fits in, or your can do it right with a mill or drill press and endmill bit.

Or just buy a new stock meant for your action.

>>1049564
It can be done, but not like you're talking. >>1049565 is right, if you try it without some inletting screws, inletting black, a couple of chisels (or VERY VERY FUCKING CAREFULLY with a dremel, but NOT advised!), and some practice inletting, you're probably going to fuck it up. If it's that different of a stock, you're probably going to have other issues as well: barrel channel, any sort of bolt recess, safety recess, trigger group inletting... A dozen things, really. Look it all over again anon, and decide if it's worth it. Basically, I'm telling you nicely to listen to the other anon. You'll fuck it up.

>>1049563
Interesting. I believe you, yet have two "issues." 1) My gut tells me the decomposition takes some time, years probably, and on a non-heirloom firearm it may not matter, though it may as well, I'm just not sure. 2) I'm going with the brass buttplates had more to do with looking pretty and showing the class of the owner than stopping decomposition. They're easier to inlet, too. Cheers anon; you seem to know your shit, and it's nice to have someone here that knows a little about this stuff.

Can I use ratchet straps/clamps to replace proper wood clamps?

>>1049628
Yeah, it takes a bunch of time and it actually has to get wet like they did in wartime. Its not simply a metal-on-wood contact that causes the rot and deterioration, but steel rusting against wood after getting wet causing rapid rot. See the old mosin nagants with rotted buttplate screws and butts. Its why the buttplates are usually replaced in the refurb process.

>>1049175
That's hard to know, because if you test a varistor it will blow up. But I wouldn't be worry about it, it's pretty hard those things fails.

>>1049747
OK. If the varistor doesn't works, the thing will simply don't do anything other than passing energy?

Basically a spring loses its springyness through compression and release cycles. Generally, this is through aging and use. Replacement is your only option.

Hey guys if you have only 3 states (A, B, C) and you assign them values for Q1 and Q0 (A = 00, B = 01, C = 10), what will happen to the undefined outputs with input 11 in the K-map? Do you just ignore them like they're 0?

>>1050709
Karnaugh maps relate inputs to outputs.
' states ' is arbitrary
If a b and c are outputs then you need three maps, one for each output.
If A is high when q1 and q0 are low your map will look like this with q1 on the x and q0 on the y or vice versa
X01
010
100
Output is 1 when inputs are 0, otherwise outputs are 0

>>1050735

Hello there!
I have a project for which I'm going to need the purest iron I can find. I'll need a relatively thin (about 1 mm) square iron sheet (about 20 square cm/ 8 square inches.) and an iron rod of about 5mm diameter.
Is it absurd to aim for 99.9% purity or could it be treated in some way that prevents it from oxidizing all the while keeping the purity?
Also, would you recommend smelting iron powder or could I manage by using scrap metal?

I'm a real newbie in metal working.Thanks for your help.

How much paint do you have to take of steel before priming and repainting? I'm rebuilding an old 1970s bicycle that I found in a field (pic related). I used quite a lot if the Aircraft solvent but the results have been patchy - the grey is steel, the pink is original primer and red is paint. Do I need to get down to bare metal or just get the surface far enough down to old primer that the surface is relatively smooth? I imagine that painting over a "chipped" texture will look bad.

>>1052973
brush-on gel paint remover

>>1052973
You could paint over old paint and primer, but the big gamble is if the new paint will stay on, look decent, or flake off and look like shit in 1 month.

A paint remover like citrustrip will work if you want to use a chemical. Otherwise, get some steel wool and stroke those tubes down to bare steel. Bonus points if you have an angle grinder or bench grinder and get a wire wheel.

Either way, mechanical removal of the paint will be necessary.

I'm looking at buying a used popup camper made by Four Wheel Campers. These things are usually quite expensive and sought after, and since this one is pretty cheap and has been sitting for a while I'm suspicious it might be in terrible condition. I'll preface all this with saying I am not handy at all and probably asking some stupid questions.

The seller says it has two issues - rust on the outside latches and it needs a new headliner. If this is as simple as buying some RV ceiling fabric and attaching it on then that's fine, but if the insulation and ceiling are severely damaged then that's another thing.

Also is the rust on the latches probably not the only place that would be rusted? Right now I'm relying on the seller being honest and not wasting my time since I've told him I'm several hundred miles away.

I've been reading up on used campers (and this specific manufacturer) on other forums, but any input here would be appreciated.

Just looking at the corrosion on the galvanized metal, rust on those deadbolts, its likely the guy took it to the ocean all the time. Ocean weather eats away materials. They're probably okay to use for a few more years, but replacing them will be your best bet against failure and unsightliness.

Headliner material is relatively cheap, and you don't necessarily need to be going back with fabric, you can go back with a rigid material like 1/4" paneling.

RVs, campers, boats, laborday toys, and the like are all huge money pits. Just be ready to put a lot of TLC, elbow grease, and some money just to maintain the thing year after year even if you don't use it for camping.
