>>34808836
Honestly the easiest with just a hand drill and Dremel are poly lowers.

>>34808836
>>34808933
>>34809317
considering the poly receivers with disposable jigs are $80 wouldn't it just be more worth it to get a $50 shipped receiver and pay the damn $20 transfer?

Any recce for calipers in the 30ish dollar range?

>>34813344
go to harbor freight and buy some cheap digi ones for that price range.

>>34813621
google used micrometers and you'll see that most of the are banged to shit.

I was lucky as hell when I got a set of pristine mitutoyo micrometers off ebay for $150

for accurate and reliable tools you're going to have to pay $100 and up.

What do you intend to use this caliper for?

So used calipers unless pristine are garbage? How do you know when to replace yours, like every three years or something?

>>34813800
>So used calipers unless pristine are garbage? How do you know when to replace yours, like every three years or something?

pretty much

I have standards which I use every time I use them or my instruments for the day that tell me if they're reading exactly zero. If they aren't or I can't get them to work I throw them out. I still have the same set of calipers from when I started doing this about 8-10 years ago

"buy good tools and they'll last forever" is not wrong in metrology.

>>34813871
Thanks for the advice, so is there like a hierarchy of calipers compared to digital, dial and slide type? Seems to be a lot of decent condition slide type micrometers but they are probably being offloaded for a reason.

Not trying to second guess you, just really ignorant and poor...

>>34813949
digi is higher recommended because it's just easier and the tech has gotten much better in recent years.

just buy a harbor freight one if you're so poor. more than likely if you need anything better than that you should have no qualms in spending the money on it and other, more accurate tools.

>>34814038
I'd rather not spend multiple drives back and forth from harbor freight so Mitutoyo it is.

So should I buy a gauge block to make sure it's calibrated or just trust it?

>>34814150
nah, should be good. just remember what I said. buy from reputable sources or else you might get a knock off.

Actual metrologist fag here.

The type of caliper doesn't really matter in terms of accuracy, it's much more quality than type (vernier scale, dial, digital).

Bottom of the barrel avoid if at all possible-tier
>plastic
>no-name chinese import discounted

Cheap but mostly functional (usually)-tier
>cheap brand name calipers like from whatever hardware store, harbor freight often lands here or in previous category

Whatever, it works but don't expect miracles-tier
(these are the lowest tier that's accepted in the usual machine shop. They're fine for light use)
>asimeto
>Insize
>Igaging
>Accusize
>Fowler
>Shars

Professional-tier
>Starrett
>Mitutoyo
>Brown & Sharpe
>Etalon
>Tesa
>Interapid

Honestly for calipers, unless you use it a LOT every day, stick to the middle two categories (asimeto, fowler, etc). Try to get some deals on a better tool if you can, but having a cheap one to scribe with is not a bad thing. I would suggest a middle of the road vernier scale caliper, as it will work without batteries obviously and there's nothing to fuck up unlike a garbo digital or a cheap dial caliper. Downside is that they're "harder to read", but if you're poor, then you have more time to learn how to use it.

in b4 less accurate/more accurate

Not really. Even the highest quality digital calipers are basically as accurate as an average whatever. A digital might read to 0.0005", but if you trust a fucking caliper to anything past +/-0.002", you're going to get bitten hard sooner or later. They are NOT super high accuracy devices. Anything requiring more than that is micrometer job regardless of how hard you can pound your fists saying "but my X caliper is always right on". Trust me, a caliper of any kind and any brand is not to be trusted if +/-0.001" or better is critical.

>>34814230
sup, what kind of dial indicator do you think I should pick up?

I was thinking about a starrett or a mitutoyo, but it would mostly be used for checking tool run out, and the work in a lathe.

I have a bestest test indicator w/ a noga base for the real precise stuff.

>>34814150

Hey goys. I don't like to come here to have you hold my hand through how to do shit. I don't like being a tittybaby that has to ask people "omg what should I do?! I'm an incompetent retard that can't make any decisions by myself!" But I've reached my wits end.

I have this ak74 barrel, and attached to it is a rear sight block. The block is pressed on crooked and I need to remove it but I can't beat it off with a hammer, and I can't properly set it up on a press because I can't figure out a way to rig it so that the force is being distributed straight up and down instead of hinging on the block. I need to support both sides of it if I'm going to press it off, but I can't because one side is just the thin metal area that wraps around the barrel. How would you niggers get out of this calamity?

>>34814309
Plunger type long-travel (0.001" scale dial, 1" of travel) is whatever. They're like the calipers of the indicator world. Caliper post above is basically relevant, so if you use it a shitton all day erry day it's worth splurging on a Starrett. I have a few cheap ones for any business where they might get dirty or banged up and a good one for general use. Anything from the big three really, but the average name brand will do just fine.

Test dial indicator is a bit more personal. These typically have sub0.001" resolution, and very little travel; generally under 0.050" of total travel. Bestest is good obviously, my personal go-to is the Mitutoyo 513-512, it's a 0.0005" pocket test dial indicator with a very long probe and a long, slim body. The scale lines for each 0.0005" increment are very far apart with a fine indicator needle, so the accuracy is excellent even if it isn't a millionth indicator and the design means this particular test dial indicator can indicate places where no other indicator could possibly reach. It's a clutch type so that might not be your particular bag of doritos but I like it that way, it's a bit less confusing when dialing a hole and flipping forward and backward with a mirror and shit.

For daily test dial use not requiring millionths, I honestly don't look any further.

>>34814406
Clamp barrel in aluminum, brass, or lead vise jaws. With a big adjustable wrench, start twisting the block while pushing it off. As you rotate the block, your downward force will slowly move the block until it travels off the press fit area.

Do it slowly and squirt oil liberally on it, if you try to go too fast you can friction-weld it in place.

Polymer 80 is better tbqh. All polymer lowers are fucking garbage but polymer80 reinforces the area where the buffer tube screw in which is the weakest part of a polyshit lower. Just buy an Anderson though. Literally the only reason to buy an 80% is if you are a fucking retarded nigger that buys into much ghost gun hype.

Getting close, just a few questions

Firstly, the fuck do you do when collets get stick in a mill? One of my coworkers said to loosed the drawbar a bit and smack the top with a deadblow, which worked once but the next time it got stuck it doesn't seem to want to go anywhere
Second, for coming back through the corners I didn't have any carbide 1/8th mills to use, and 1/8th HSS seem to snap the exact moment they contact the steel of the trunnion/the brazing between the receiver remnants and trunnion. That being said, I do have a beefy Dremel 4000 something at home, think that and the stubby carbide bits I have for it will work decently for the last of this?

>>34821201
1. Smack the fucking top of the drawbar harder.

2. WHATEVER MEANS NECESSARY

>>34821201
Use a lead, brass, or copper mallet. Not a deadblow/plastic hammer.

The sharp strike with a relatively hard substance will be much better at freeing a stuck taper fit. You can use a steel hammer, but it'll eventually peen over the drawbar.

>small endmill snapping in corners
Try plunge milling with a small radial step-over. I've successfully gotten corners in parts with a 3/32" diameter carbide that was 12D, and a 1/8th that was 16D. If you're wondering what that means, it's a simple way of showing how long the endmill is relative to its diameter, so 10D would be ten times as long as it is wide. Basically, you "drill" slowly with your endmill, but you only cut a little bit at a time, like taking slivers of hard butter with a knife instead of trying to stab the middle of the butter or trying to cut the butter in half all at once.

>>34821693
>>34822375
Thanks, metal hammer and harder hits were the ticket

On the Dremel question, I will clarify that it was less of a "Will it work?" and more "Is this a good idea?"
Regardless, will have to wait until tomorrow

>>34822479
Normally, hitting "harder" isn't really the ticket. Hitting faster/sharper often ends up being the way to get a taper unstuck.

I have a long handled brass mallet in my toolbox for that sort of thing, you give it a good sharp snap and it unsticks 99.99% of everything. Sometimes there's shmoo or the taper is just really stuck (for example, if there was for some reason a large temperature difference between the male taper and female taper) and it requires a bigger hammer and more force at that point, but usually that's fairly rare (I would hope).

I've lost interest in shooting now that I've started building. Is this normal?

not really corroded, just a black mark, it happens everytime i shoot the damn thing, and it also got on the leather of my holster n wknt come out of that either, so like do i do the whole gun in the polish? i got some but it says nothting about nickel and i dont wanna fuck it uo

>>34828618
First, sober up before working in your guns and second use some CLP on a rag to rub at it and clean it after you shoot it

Pics of the mark? Does it feel rough?

Don't over polish it as it works by removing a fine layer if metal.

Got myself a problem here. Bought myself a IMA Martini-Henry MkIV about a month ago. The rifle under all that grime is beautiful besides for one problem. The cleaning rod was so pitted and rusted that it snapped in half. After 3 weeks of soaking it will not moving still. Any tips? Also will that crack make it unsafe to fire? It only goes about 4 inches up.

back when I made that video, they were super easy to do, and were the easiest 80% receivers to complete because the middle pocket just had to be weakened and then pulled out. You could do the whole thing with only a dremel.

Then they got ATF raided n sheit, and they no longer make receivers like that anymore

I really want to learn to tig weld,. where do i start?

>>34836097
Honestly I would take classes or get an experienced person to show you. mig you can learn on your own but stick and tig have a steep learning curve at first and it helps infinitely to have a knowledgeable person to walk you through the process and help you develope proper habits in your technique. You can buy a rig to practice with and try to learn yourself but you'll probably develope bad habits and be a shitty welder. The best way would be to go to trade school

So I have successfully mounted a picatinny rail to an Italian Carcano rear sight. With only minimum cutting and grinding. Proud of myself.

>yes, rifle was fucked before I got ahold of it, posted some pictures a few /gg/'s ago

I took one of those shitty AIM Mosin mounts that fit into the rear sight, cut down the Carcano sight flush, grinded on the AIM mount for a good fit, and mounted it using the provided screw and nut just like it was going into a mosin. Near perfect fit. This is a cheap scout rifle type project so nothing of real value lost. Got an old red dot that's getting mounted to it, or maybe an EOTech Clone I have laying around. Now just have to get some parts for the bolt and the gun will be done.

I just don't have the time or money to have someone teach me honestly

>>34836333

>>34836357

I've only done mig welding but want to learn tig. friend is wiling to dump a linlcon tig on me, but I have no idea how to do it. I work a regular 8-5 job, so time is kinda lost on me.

>>34836405
If you have time to practice you should have time to practice properly, I.e. Your tig welding friend showing you the ropes. If you have never tig'd before it really isn't something you can just pick up and start learning yourself. You'll waste your time if you jut watch some YouTube videos and try to learn with no help.

You right but it's the difference of spending many hours and a lot of money on materials to get the idea vs someone walking you through the motions and only taking a hour or so to get it. Once you have the general idea it takes A while of consistent practice to refine your technique

I cannot think or comprehend of anything more cucked than having a daughter. Honestly, think about it rationally. You are feeding, clothing, raising and rearing a girl for at least 18 years solely so she can go and get ravaged by another man. All the hard work you put into your beautiful little girl - reading her stories at bedtime, making her go to sports practice, making sure she had a healthy diet, educating her, playing with her. All of it has one simple result: her body is more enjoyable for the men that will eventually fuck her in every hole.

Raised the perfect girl? Great. Who benefits? If you're lucky, a random man who had nothing to do with the way she grew up, who marries her. He gets to fuck her tight pussy every night. He gets the benefits of her kind and sweet personality that came from the way you raised her.

As a man who has a daughter, you are LITERALLY dedicating at least 20 years of your life simply to raise a girl for another man to enjoy. It is the ULTIMATE AND FINAL cuck. Think about it logically

>>34813665
ebay or pawn shops. Dont buy cheap measurement tools because they will fuck you in the ass when they measure a dimension incorrrectly and you end up ruining a workpiece.

>>34822479
If you aren't aware you should never insert a dirty collect into the spindle. Clean the taper hole and then use some light oil on it.

You also need to spin the HSS slower than the carbide. Its a different animal. try 500rpm or so. You will also need center cutting endmills to effectively plunge cut. Plunge cut SLOWLY or you will constantly break tools

>>34855111
Getting cheap digital calipers is fine because you should never be using calipers for anything other than getting a rough idea anyway. My instructor calls them "guessing sticks". If it's imperative that you get an accurate measurement, then you should be using a micrometer anyways.

It is more versatile, except for the part where this is a gunsmithing thread, where tig is the ONLY acceptable answer, and mig builds bad habits when you start tig.

I know because I've lived it. I started production style mig, and now when I use tig (the only welding we consistantly use at my current employer,) I am behind the 8 ball because of learning the easy mode welding first.

don't forget auctions. old fuckers often have very nice tools, and their widow sells them for what he told her he paid for it. I have bought 2 Starrett mics and a Mauser vernier caliper at auctions, and never paid more than ten bucks.

I use one of the starrets and the Mauser calipers at work when the feeling strikes to use tools older than I am. I checked both against gauge blocks after a thorough post purchase cleaning/lubrication, and both were within half a thou.

TL;DR go to auctions on Saturdays, hang out with old fuckers, buy pro tier tools cheap.

pic is gauge plates, one before and two after grinding to +_0.0008 inch parallism on the major faces.

>>34863175
I honestly find TIG to be easier than MIG. I'm no expert welder of anything but MIG just seems really sloppy to me. I feel like the spool feeds too fast and there's just spatter everywhere and everything looks like dogshit. TIG seems more delicate and you can sort of take your time with it. Stick is fucking impossible, I don't know how the fuck people do that shit.

>>34863471
I hear ya. be thankful you can into TIG so easily. we have MIG at my shop, and use it from time to time, but in a mold shop TIG is really the most useful type of welding. my boss can lay down layer after layer of weld and when we go to machine it, there are literally no voids. I wish I was that good. my TIG welds look worse than my MIG welds.

I thought you just needed to strip the old receiver from the parts you needed?

The original receiver was saw cut when demilled
There are still remnants of the receiver in both trunnions, so I've got to remove what's left before putting it on my new receiver blank
Oh yeah, and it's brazed

>>34869527
can you use a dremel to grind or use a cut off wheel to get it off.

Will probably be doing just that to finish this out, tightness of the corners make it difficult but I'm gonna grab a mallet and see if those little pieces are at least weakened enough to break out

you've got bigger problems than saving those screw holes. I'd start with ditching the entire dust cover mount, then the stock, then the shitty plastic magazine and possible shit tier muzzle break. Honestly I'd just throw that whole rifle in the trash. Probably costs more to unbubba than it's worth.

Also any of you AK goys know what size drill bits I should use to make the holes for the pins for all the various barrel components? Polish kit b t double u

Small update, tried a different gun smith and they said they'd do it no problem. They're also going to install a new magazine catch so it can convert from .40 to 9mm as well (I have a 9mm barrel that fits already, but the 9mm mags were falling out sometimes when cycling rounds), and all for a fraction of the cost of what the other guy wanted just to work on the barrel.
Guess it's all about finding the right person.

>>34814406
This is how I would do it. Alternatively, you can make a custom cut-out in a block of steel to match the barrel/sight base profile to use it as a base and press against it. Unless it's stuck on there real good, you'll have no problem with an adjustable wrench in my opinion, just lubricate and go slow.

>>34878878
It's stuck really extra good. I've tried pic related and even tried putting the block inna vice and twisting the barrel with a pipe wrench. I'm just gonna get a tool where I can put it in a press and push it out.

>>34878945
>>34878878
What I meant is using the adjustable wrench as in a press, to press the barrel out. You won't be able to rotate it, it needs to be pressed out

>>34882829
Is the recoil spring one with a guide rod so it doesn't get hooked on the trigger? How do you get the firing pin in place? Where is the barrel trunnion? Does this design really even need a spring for the bolt because it is single shot? This design really doesn't have potential for anything. Maybe you should draft up a pistol caliber carbine because it doesn't require a lot of pressure checks.

>>34882829
If you want to design guns, become a mechanical engineer. Gunsmithing really has very little to do with what you're doing.

>>34882829
How does the main spring clear the dogleg in the firing pin?

>>34884206

Do the screws turn at all? They might just be loctited in place. Fudds tend to do that. Let some Kroil soak in and blast them with heat before trying again. You can fill in the holes with TIG or solder.

I think the Obama years stimulated the gun market a lot for the last 8 years with all the constant panic buying. Unfortunately the only guns that are now cheap and readily available under the god emporer are generic trash like ar's and commercial garbage bolt actions and plastic pistols. The import sanctions have only gotten more strict under him ;_; I think the days of surplus firearms are waning unfortunately.

>>34904676
Well the import restrictions were left over from Obama's time. Sanctions put in place by Obama that were put in effect due to Molot's being sold to Kalashnikov Concern.

I think that panic really helped drive the market right around and after panic, it was pretty good even before but things were so much cheaper. I miss running tables at gunshows and buying $50 mosins off sellers before they opened up the gates to the general public.
