3/4" Mini... Airsoft/PB

Unread postAuthor: frogy » Sun Jan 20, 2008 12:02 am

This thing is a work in progress of my many projects...

I highly doubt this can move a paintball far, but I'm going to try mini-propane injection... (Hopefully)...


If this doesn't work correctly, it's already pictured with an airsoft barrel that should work fine... This gun may just meet the trashcan though :)

I still need to fix in an igniter... My last igniter was ruined whilst I was trying to glue it in... I made the mistake of pouring adhesive into the internals of the igniter, so it was ruined, and I had to chisel the remains of it out of the gun...

Edit: Gun update
Made airsoft barrel... 5/16th inch brake line hot glued\tefloned into a 1/2" hole....

The Schrader is at my other house... Thinking about using a butane venturi for fueling...

I think it would be near impossible to make a fuel meter that would measure propane that presisely but I say you should try anyway. Shouldnt put you back to much because of the size.

I've made a hybrid out of 3/4" PVC once and it worked well, with Vinyl tube as the meter pipe :)

I'm planning on installing a Schrader on the gun... Metering propane\butane with a vinyl meter tube... and dispensing with a regular fill valve...

Gas mini's are fun! (and cheap)
