Alright guys, for my next project, which I don't know will happen or not, I'm going to be building a homemade plunger and plunger tube. Problem is, I can't decide on how to make the piston. I'm thinking about just testing O-rings at the hardware store and see what fits nicely in 1" PVC, but it's going to be hard connecting the O-ring securely to the piston without being able to mold plastic. It looks as though wrapping some 1/2" PVC in e-tape worked nicely for Boltsniper's P99, but if you guys have any other ideas for making a nice airtight piston they would be greatly appreciated.
An idea I had a while ago, cut slits in PETG and wrap it tightly in electrical tape. With the ID of the PETG smaller, you can have a constricted section of the barrel that allows the air pressure in the plunger to build before firing the dart. I modded my Triple Shot and tested it with a normal PETG barrel and this barrel, and I definitely got improved results of about 5-10 feet. I encourage you to try this and see if you get similar results. I already wrote up a short Triple Shot mod and more details about the contricted barrel for NW, now we're just waiting for Grinch to post it. Feedback?
I finally decided to get off my lazy ass and finish one of my old projects. This gun has been made from scraps of many assorted things, but the valve is from a supersoaker (CPS 1000) and the pump is from a Larami 2000 (Sm5k lookalike). In case you were wondering the T-coupler on the back makes up most of the airtank. Range is very good, quite a distance past 100 feet, but the main thing I love is the velocity and accuracy. I have never seen another gun shoot with with the same velocity and accuracy as this one. ROF is also very good, thanks to the breach that I cut out of the shell. The only problem I have with this gun is that the pumping is a little awkward. Any input on where to relocate it is gratefully accepted. I couldn't stand the bright yellow pump handle, so that and the EaB trigger got painted black.
