Cannon construction

It is important to construct your launchers with care. This includes:

• Using pressure rated (NSF-PW or NSF-61) fittings and pipe, especialy in a Pneumatic Cannon.
• Solvent welding correctly
• Using pipe of the proper pressure rating, eg. sch 80 in a Hybrid Cannon.

Under no circumstances WHAT SO EVER should you use cell-core or unsleeved thinwall pipe.
