I'll crunch some numbers once I get to the cad/hardcore cad (paper >.<) stages.
We're generally disapproving of acetylene for safety reasons, favoring fuel/air hybrids for greater power that is easier to control, but if you can build it with a sufficient safety factor it would be fairly awesome.Crimson wrote:I though I'd throw this out here and see what the diy cannon community thought.

I'm thinking 1.5"+ thick mild steel, but I have yet to figure out pressure ratings and safety margins for anything.

Well, I guess I'll start with propane and see where we land at there ¯\_(ツ)_/¯Zeus wrote:Myself, I would avoid acetylene too, but for a totally different reason. If you stick to oxy/propane(or your hydrocarbon of choice), you can always pressurise the chamber for mo power. You already have a rupture disc, regulators, gauges, etc. It's not a whole lot harder to add twice the fuel and pressurise gently with oxygen. Or given that fuel/air mixes tend to offer more power by unit of fuel, then just pressurise with air.
