I am interested in building a tennis ball cannon.

I know there are probably many different designs.

Could someone please E-mail me plans for a really
simple one.

Thanks  

Gary

If you want to build one that has no risk of bursting in your hands,
use propane cylinders.  The ID of a common propane torch cylinder is 
just the right diameter for a friction fit.  Cut the ends from
several with a pipe cutter, weld them together and you're ready 
to fire.  If you weld this "barrel" to one of the short, fat propane
torch cylinders whose top has been cut out with a hole saw and use
the short fat cylinder as a cobustion chamber, you'll achieve
phenomenal range.
