Hi all, i got a bug up my but to build a cannon, ive built telescopes for five years on my lathe and mill,
i had a piece of stainless steel kicking around so i made a morter,
sub-chamber is 1/2 X 3/4 deep, front chamber 1 and 3/8
over all length, 4inches, 2 1/4 diam over all.
i fired it without anything in it, ffg half of the chamber,,woosy,,,
fired again full, with toilet paper wadding, Pop,,, cool,,,
then i found out that a PVC round end-cap slides into it nicely,
loaded tiny bit of toilet paper in the powder chamber to keep it in,
lowered it level at my chain link fence,
BANG,,, little louder than a fire-cracker,,, end cap flew 20FT,
another round straight up, full load, 40FT, cool,
NOW, ami gonna blow my self to bitts using stainless steel??
i am also looking for info on building a Howitzer out of 1018.
4inches in diam, and no longer than 18 inches, its all ive got on my lathe
for room.
how large of a bore can i safely have,
id idealy want something that booms or cracks louder or as loud as a M80
so im all ears for advice,
i cant shoot beer-cans as i live in a couldisack, but want something for the 4th, and newyears,
thanks for listining, hope im not comeing across like the idiot i am.
oh ya how do i add a pic of my morter???
clear skys, johnp
