Construction was slow but as I found more time, it started to piece together very nicely.
Specs
-1/2" gas pipe propane meter/direct injector
-4" x 2' chamber
-1.5" x ~6' barrel
-Custom wood handle
-Bracket mounted chamber fan
-Standard single arc pezio ignition
-Threaded barrel to chamber connection (to be replaced by cams once I find some)
Some pics!
