T-Piston Airgun with Collapsible Stock
Posted: Fri Sep 25, 2015 2:24 pm
Wow, two posts in one day. It's like I've risen from the dead.
Been browsing gun ideas again, now that I have most of my tools with me at university I should be able to make something. I noticed while looking around that the last guns I made were never posted to the forum, or anywhere for whatever reason so here is what I made last spring break (long video):

The idea was to take a relatively small T-piston off of an old broken gun, fix it, and get it to actually work reliably. I went ahead and experimented with some woodworking and what-not, and ended up with a neat little toy. Not nearly as powerful as my older guns but I learned a lot so that's always a plus.
1" tee piston. The piston itself is made of sanded 3/4" pvc with a rubber sealing face. To get this design to work, the 1/2" pilot housing was filled almost entirely with hotglue to reduce the volume; otherwise it's not efficient enough to draw back the mediocre piston.
Currently looking at making a hammer valve for the first time. I know I can make semi's using a QEV + slide valve but I like making the stuff myself and learning along the way, so I'll hopefully be posting a tutorial or something in the future on a 1/2" pvc hammer valve that newbies should be able to use effectively in a semi-auto design. Already have it drawn up and seems pretty straight forward.
That's it for now, just thought I'd drop in and say hey to everyone.

very Metro 2033, interesting build. Deserves some wood staining and metal finishing to complete the post-apocalyptic look.
(all at once?! I must be crazy)
