PPSh41 Semi Auto Reweld Build - Bolt and FCG Progress
Просмотров 6 тыс.Год назад
Check out additional videos on my rumble account here: rumble.com/user/JPMachine Did some work on the bolt and FCG. Pardon the mess, it’s how I work, I’ll clean it up later. 😉 Spoiler alert, my shroud extension idea didn’t work. I’ll make a form jig to press some flat stock around the mandrel I made. Next up is the barrel I think. Turning the barrel with the extended shoulder now!

Where did the trigger group come from
The best one you can get is from freedom machine. freedommachineworks.com/product/semi-auto-pps-43-fire-control-group/
The best one you can get is from freedom machine. freedommachineworks.com/product/semi-auto-pps-43-fire-control-group/
I remember you having a video on the install of the auto shelf and modification to the trigger group. Is there another platform where those videos are still available?
Yeah, check on rumble!
@JPMachine thank you so much
this is great, but did you ever document pressing the barrel into the trunnion and setting the roller gap? that's the only thing i've really been having a little trouble with - being a perfectionist i've been trying to get that gap on the low end of the tolerance and i keep blowing by it with my press
Yeah that video got pulled I believe. It is over on rumble though. Google “JP machine rumble” and it should find my channel. Sometimes you just gotta push it through and start over, otherwise you can try whacking it with a mallet to set back a few thou.
How has it been holding up? I've been thinking of building one but I heard cases of CETME Ls breaking
It runs great actually. I finished it up a while ago just haven’t had a chance to do any more videos.
GREAT JOB
Nice work
Great set of videos!! Extreme helpful. I push my barrel all the way down to the flange and I gotta use a feeler gauge, but it looks like there was no bolt gap and it was really hard to get the bolt to come out of the Trunon.
You're very talented? What welding machine do you use
just randomly found your channel thru VZ61 and PM63 build videos, must say nice metalworking
Nice.
Refreshing to see a non believer. Most people believe in the shaving cream rule "the more you use , the better it works " instead of the brylcreem rule " a little dab will do ya "
Are you a wizard?
Haha not quite!
Very nice.
Do you know what’s a really good mig welder for a good price and easy to use any recommendations?
There are two areas I think you should address that I can't seem to find too much info on. Firstly there's the weldment insert in the back that sits between the two rear takedown pins. That insert will not allow a cetme c stock to fit. I've found it best to use just the two steel standoff bosses right on the metal receiver with no additional weldment, or trimming the weldment insert almost in half. The other thing that I rarely see documentation of is the use of the paddle release without doing naught stuff. I think some simple measurements for the bushing and pin you used to avoid the dreaded 3rd hole violation along with video of how you did it would be super beneficial. These types of rifles suck pretty bad without a paddle when it comes to reloading. I figured out the paddle for myself, but it seems like most of the cetmes, g3s and ptrs don't have that because of the tightrope that needs to be walked
Thanks! Yes the rear weldment thing is annoying and basically pointless in a semi build. I did have a video on the paddle but YT has been slowly deleting my videos. That video with the paddle is on Rumble, just search for my name.
@@JPMachine Thanks man! I'll check it out!
Hi.why does the push bar have the .75 flats? Other jigs are all round
Saw that dimension online, the other thing to use is a 20mm round bar instead of what I used
@JPMachine 20mm that's smaller than yours, right?
@joeygabriele71 just a touch yep, but that’s the real dimension if I remember correctly
@@JPMachine thank you
Voce tem o plano em tamanho real?
Great video…Question what do you use for your lathe work make & model also what do you use for your welding setup. Thanks KR
Right now I have a precision Matthew’s pm1130v. Great lathe. I used to use Mig for all my stuff but now I am 100% with an alpha tig 203xi and it works great!
Can an hk91 locking piece be used in a cetme c 308? If not, why not?
Not sure honestly!
Do all the parts that it needs come into the kit?
No, you’ll need a semi bolt conversion and a barrel.
@@JPMachine ok thank you just ordered one
@@blascowitz3083 Whered you find it?
@@JPMachine bowman
@@JPMachine the parts kit
So was this demilled, like cut barrel and reciever and you welded them back together?
Yep, it was basically reduced to scrap metal…legally. Then converted to hammer fired closed bolt semi auto instead of open bolt full auto
Do u think using a mild steel flux mig welder would produce decent results ? I have a flux mig welder and lots of experience on sheet metal, etc just wondering if the gas mig is a major difference
Flux will work, but messy. Mig will work too, a bit cleaner but Tig is best. I switched to tig about a year ago and now use it on everything!
Really nice job, great craftsman. Thanks
Thank you very much!
Built a few of these....first thing i did for the bolt was made an aluminum fixture that holds the bolt in position, then that goes in the 4 jaw chuck. A couple aircraft length drills and works perfect and repeats every time. One tip, get the drop in trigger unit if you can because trying to make a Remington 870 trigger group work in one of these is very difficult
Great build!
Wow! Freaking beautiful!!
Great work man! The end of part one was amazing!
How much to do some work on my kit?
I'm sure someone has mentioned this or you already know, but for the electo-etching, you're better off using sodium carbonate (washing soda) for the electrolyte rather than table salt; with table salt it's possible for chlorine gas to be produced which is toxic and can rust anything steel.
Interesting, thanks for the info! I did not know that!
@@JPMachine np, your build look great btw!
Outstanding....
I really wish I had seen this before trying myself. I used an old piece of galvanized pipe, a hammer, hammer and a vise.
Disqualified
Ate you still doing work on pps43, if so how do I contact you
Yep! Email me at jpmachine607@gmail.com
I’m starting my PPS-43 and will be contacting you soon for a bolt conversion. I’m assuming you’re Tig welding your builds. Could you please tell me what filler rod you are using? I was going to use my mig but this is a good excuse to get a Tig. At least that’s what I’m telling myself. Trying to gather as much information as I can. If possible what color tungsten are you using as well? Thanks.
Just a bit of a pointer on a different way. Instead of a cricket you can get a cheap laser. Stick the stencil to the metal then laser etch it. After that you chem etch it. Pretty solid method without putting out all the duckets for a laser that will actually do metal. Solid video either way
I actually just bought a fiber laser that does a MUCH cleaner job than electro etching!
@@JPMachine for sure, but the price of admission kills it for most home gamers making electro the way to go for most.
Looks great!!!!
How exactly did you get the pivot pin and barrel pin out? I tried to get the pivot pin out with an air hammer and it won't even move. Did you have to grind off one of the mushroomed ends or did you just force it out? I don't want to bend anything or break something trying to force it.
Pivot pin usually just pounds out. I try to drive the end through that isn’t as mushroomed. You may have to grind the end off and trash the pin though. Barrel pins are tough. They will either pound out with a hammer, from the top down, or you’ll need to center drill it out 3/4 of the way through and either pound it out or press it out.
What size rivets are needed for the Trunion? After putting a new barrel in?
I use taper pins, they are #5. Could also use a 6mm pin like factory if desired
Picked up a new subscriber today. Just the stuff I have been looking for.
Awesome! Thank you!
Great job man, love all the details, thank you!
Much appreciated!
I love my PPS43. It doesn’t have a threaded barrel cause it’s original 1940’s but I do have it re chambered in 9mm
Nice!
Do the magazines still feed with 9mm?
@ yep! No issue with original mags.
@randykricke8685 yeah mine feeds 9mm no problem. Got vids of shooting on my channel too
What grits should you use for the belt sander to get a smooth finish?
For final around 180. For the main weld grind I use 60-80
You should be expensive you are an artist my good man
I need an upper receiver and 7.62 barrel and finish mine.
Nice work, thanks for the vid, I have a Century and a kit, now I have the itch to put the kit together.
That's a beautiful "chopo". Well done!
Can you do this on a reciever that is already blued?
It will etch blued steel for sure. I’d be super careful masking the other areas though… not sure what the solution will do.
Fantastic video and job on that piece, you do great work! Thanks for the inspiration!
Thank you. This is the best and most simple jig that isn't janky that I've seen so far. I'm gonna try this. I'm gonna try doing an hk21 build. I've done a mp5, mp5k, and a mp5sd and gotten better each time. I'm hoping to being close to factory quality with this next build and I'm positive this'll do better than conduit.
Looks like a very fun project.
Was that 1" square tube? I tried a unistrut jig, and the unstrut was flexing out making the receiver skewed. Looking for a different method.
I think it’s 1.25”. I had it laying around from years ago. It works great!
