Advanced Combustion GB Launcher
Hi spudfiles, I used to frequent this site with my creations but then things came up... (girlfriend, jeep, work) But now that I'm settled in after my first semester of college, I decided it was time for something new!
84" long, 1.5" SDR 21 barrel
2" aluminum camlock
2" exhaust ball valve (Overkill, I know, but it's how I wanted to do it.)
Fan at back of chamber
Single spark gap provided by stun gun internals
Non-serviceable chamber (I, too, like to live dangerously. Ha!)
165 cubic inch chamber
2.75 cubic inch propane meter (3 way valve, no regulator)
Slightly over 0.8:1 c:b ratio, but still surprisingly quiet shooting golf balls.
Little bro posing...
*shoutout to starman for inspiration on paint and probably much more!
Boom! The classic potato gun harnesses the combustion of flammable vapor. Show us your combustion spud gun and discuss fuels, ratios, safety, ignition systems, tools, and more.
