What size cylinder?

[DarkShadows]

What size cylinder should I use to make a 55 gallon drum hop? Im thinking a 2 inch bore with either a 2-3 inch stroke. Any suggestions?

There's a cylinder bore size calculator here (http://www.scaryguys.com/aircylcalc.htm). That might help determine the bore needed.

an empty drum does not weigh much. I am sure that a 1-1/8" cylinder would be sufficient. As for the throw, it depends on how much hop you need. Are you planning on positioning the cylinder near the center or the edge?

Thanks for the size calculator Scare.

I plan on welding a mount on the bottom, so I can have the cylinder shoot out right through the center. I dont want the drum to tip over if shot to high, just want it for a little startle affect.
