- Well yesterday I built a new cannon! All ABS with spark ignition, we
were shooting potatoes straight up to about 800-1000 feet high! Use
spray paint for fuel an this thing packs quite a wallop! Destroyed
quite a few old fence boards set up at about 15yards. When we would
miss the fence boards these things would just sail out to about 100-
125 yards from only about 3 degrees elevation!!! 42" barrel and 16"
combustion chamber, and sure is noisy! Once I get some pics of it I
can post some to the site.
