This is my large Combustion Cannon
I started off with a simple two inch pipe 6 feet long with a end cap glued on one end and a sparker from a long nose lighter. As i know now that didn't work. When i got home from the trip i took it on i cut off the end cap and got ABS fittings and pipe at the local Home Depot. I cut the pipe to 18 inches long and glued the reduser on one end and the female adapter at the other end. i then glued a length of two inch pipe into the reducer and then a female adapter so i could change the barrel or gust take it off. I then installed a twist lantern igniter. That worked pretty well for a wile until the flint ran out. Then i went out and got a pezio Electric Grill sterter from osh for about $9. I installed it and the effectiveness ot the firing.
The next Month i took it on a boy scout trip we went to a beach that had huge dunes. i was using hairspray then and i learned the hard way that hair spray acts like glue. The clean out cap got glued into the threds. We learned that the wheel on one of the cars had a hole in the wheel that the hex on the cap fit in perfectly so we could loosen it. Our best shot went about 450 yards.( i measured it with google earth).
Last weekend i got the supplies to make a PVC propane Meter. The meter is very simple and i only had to buy $9 in parts to make it. It greatly inproves the speed of loading and firing. Tonight i bought fittings to transform the cannon to a under over configeration.
