Re: Full Auto 50

Thanks, If I say I am going to do something, I do it. It may take five years, but it gets done. It was hanging up, I think, because the rounds were a little too long, (Shorter would drop in clean) and drum spring pressure weak. I can adjust the rate of fire with the variable pressure relief valve bu...

Re: Full Auto 50

Thanks Cammy! I really appreciate the compliment. I like to think that when I say I'm going to do something, it gets done. Maybe not right away... There is a slight hesitation under a full load, so I think I'll beef up the spring a bit. STG, fully loaded, 5 1/4 pounds. Probably less than the real th...

Re: Full Auto 50

Ha! It looks like we suffer from the same affliction. If anybody is wondering about safety; I used wooden dowels for the test, the gun was remotely fired and I was wearing a face shield and hard hat. I figure a small chamber hidden in the pistol grip would suffice. Yeah, it would sure save me a lot ...

Re: Full Auto 50

Thanks again for your input guys, it's a big help. Dajaro, yes, it's just a hole in a piece of steel. I made it a couple thou smaller than my barrel ID. I didn't want to ream the entire length of the barrel to 5/8th's, which I should have, like you said, "make the gun suit the ammo". Wood workers us...

Re: Full Auto 50

Thanks for taking the time to post that.

My realization was that the -air in- had to be ahead of the valve. I was thinking of extending a tube to move the seal face, but your approach may be easier to make.

Thanks!

Re: Full Auto 50

Thanks wyz, The bottle is not meant to be an air supply but just a means to; -increase the volume of air going to the projectile -by enlarging the chamber volume, delaying the time it takes to reach full pressure, decreasing the ROF.

Re: Full Auto 50

@dartguy; Thanks for the ideas. @dajaro; I thought about PEX plugs, but not sure what you mean by pvc swager, do you mean PEX crimper? @Btb, JSR, Yeah the bottle was meant to be a reservoir, but a bit of a moot point now. I feel like a bit of a simpleton and obviously rushed to throw together some g...
