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.
- Only tapping (for bolts, pressure gauges) though a double layer of pipe.
Under no circumstances WHAT SO EVER should you use cell-core or unsleeved thinwall pipe.
