Don't fire that sucker too close to the house! That volume of
Acetylene/O2 mix will create significant overpressure, could break
windows if too close.

Empirical data: ignition of a 30-quart kitchen garbage bag filled
with O2/ C2H2 mix didn't break any windows but it did knock garden
tools off the wall of a wooden yard barn that was maybe 50 feet away.
A tall O2 bottle will have aprroximately that volume of gas at
atmospheric pressure.

I would strongly suggest grounding everything while filling to
preclude static sparks, and then use electric (sparkplug or squib)
ignition.

A friend of mine actually did make a bell or gong out of a tall oxy
tank; cut the end off here at my house with my plasma cutter. When
struck with a bonger, it makes a very satisfying and
quite-long-lasting tone; it's a very high-Q resonator. Geez, if
twanged with a charge of O2/C2H2 the thing may ring for quite a while!


It will be permanently mounted on an A frame, looking just like a southwest
decor bell. It will be aimed away from the house, and aimed at about a 45
degree angle upward. Will I still have concussion issues?

With any luck!
