Collecting bits for a while, finally got round to putting them together. Mostly all used parts.
Spec:
8ltr high pressure sprayer bottle for combustion chamber(inc bends likely 10ltr)
2m long 44mm bore aluminum barrel
BBQ sparker ignition
12v Air bed blower to vent chamber
12v drill battery powers blower
Metered propane via regulator
Stainless exhaust pipe bends
Barrel opens via stainless sanitary flange fitting/clamp
Laser dot sight
Just made it up as i went along using the bits i had, no fancy calculations etc. The combo of large combustion chamber and long barrel seem to have worked. It has crazy power and chucks spuds through finish grade 3/4 plywood and golf balls clean through oil drum without it even moving See damage pics
