PPs-43 build

[TylerRitts]

Hello everyone! I just got my semi auto converted bolt back in and i am ready to start welding up my kit. However I only have one hang up. I only have a Titanium 125 flux core welder. Do you think this will work okay? I have access to a bunch of different grinding and sanding tools.

Thanks

Just curious are you building for 7.62x25? Just curious since all the cheap 7.62x25 dried up.

It would be using a 9mm luger barrel.

Nice. did the bolt face have to modified?

Hmmm. I don't believe so. I guess I'll find out when I weld everything.

Weld splatter with flux core will be your worst enemy. Make sure your welder will handle the thin material you're working on, some of those cheaper flux core welders won't do thinner materials well. Use weld splatter spray such as E-Weld if you have it handy. Knock off any bb's that stick right away.

Go slow, tack it in opposing spots and work your way in, making sure to let it cool and normalize frequently.

Thank you. that info helps a ton. Do you have a suggested wire to use?

Some good info on Weapons Guild.

Whole section for these.....

Who did your Bolt?

Use Freedom Ord. fcg?

For flux core on more precision parts, I'd go as thin of wire as you're machine will handle. That will also help a little bit in keeping your heat from spreading out as quickly. If need be, you can go back and fill in spots after you grind.

Aren't you supposed to switch polarity for flux core wire.......???

Good God all of you... just use a TIG welder. You're welcome!

I would but a cheap tig is like $700. I already own a flux.

Will do. Thank you.

Bolt and semi FCG was from a local shop.

The machine he has is a flux-only. You only worry about polarity on changeable flux/MIG machines.

I'm sure he'd use a TIG if he had one. Run what you brung.

This. A tig is out of the question currently. I also will probably only do one or two of these at best.

Mind sharing?

I have a few that need done.
Any clue If they will do other bolts......ppsh ,Swedish K etc?

 

[eldbillbo]

How much did it cost to get the bolt done?

To be honest, it was a personal friend that is a gunsmith and machinest. The semi FCG was bought online. My friend doesn't really do them but he did mine to be nice and he was also curious on how it was done.

I got lucky. My friend is a gunsmith and machinest. He doesn't really do semi bolt conversions but he did for me because he was curious how it was done. He charged me $50.
