Making a Semi-PGP

O'Lane · 04-23-2007, 10:09 PM

I've been researching these forums for quite awhile now on this topic, would like to know if any of you know any other sites that have how-to instructions on doing this, things like dimensions, diagrams, etc. are very helpful. Also, what best for doing this, the newer PGP or older ones? Thanks.

Older PGP's are better, IIRC. NVM...

The newer cartridge valve ones can be modded so you end up with a vertical air ASA on the PGP. I think Big Matt and Rainman229 (or was it Blackrain?) can do them.

are you looking to mimic palmers? or would you rather go the imp kit route? there are a few ways to do it, im looking at doing an open-bolt blow back system with a pmi1, moving the valve assembly forward to accomidate the blow back hammer and spring, just have to make a custom trigger/sear and use a kp type trigger block...

I'm actually looking at doing something along the lines of the Mrs. Palmer pistol, It would be black wrinkle powdercoat most likely and have rear and front sight grooves to except Springfield XD pistol sights. Also, anyone know were I can order the rear ASA for the PGP, I checked palmers and they're not on thier site, or should I call them? So yeah, pretty much mimic a palmer.

i hadnt seen that one before...now thats what i would call a holdout! kinda suck as a semi, though, side fed without a spring...looks like a stock sheridan back block drilled out on the other side, direct tapped to the valve...otherwise you could look into an old cooper-t back bottle setup...

O'Lane · 04-24-2007, 09:13 PM

I definitly intend on using a 10rd spring feed system on it located where the current tube setup is.

Also, I'm looking at going a slightly different mount than the cylindrical ram, I'd like to machine one from solid brass that'll have a nice fit against the main body. Does anyone have the dimension's one the regular rams, so I can base it of that and just change up the housing of the ram?

I guess what I'm really looking for is the mechanical understanding of how a semi-pgp works. From what I can tell, a ram is soldered to the side of the marker and an air line is run from part of the valve upon firing to recharge the marker. Is that it? Sounds to easy.

No, that's not it. It works exactly the same was an autococker. I'd suggest first getting intimately familiar with the pneumatic auto cocking design first before you attempt a semi pgp project. Try building yourself a couple Autocockers from parts and timing them correctly. Then you'll be better prepared to undertake a project like this.

Didn't think It was it, but I have alot of experince in paintball, pneumatics, machining and engineering, so I think I'll be fine.
