My plain jane 2nd cannon

Unread postAuthor: spudmatic » Sun May 18, 2008 4:25 pm

Here is my 2nd cannon and I decided not to go too crazy but chamber fan and metered propane soon to come. Oh, and a red laser mounted to a rail at the chamber end of the barrel, currently waiting on laser.

There is no paint on the gun it is all black and red electrical tape because I do not have the patience to wait for paint to dry :D .

It is powered by a 150kv stungun with 4 sparks.

Then your normal 4in chamber to 2in barrel. I dont know how true this is but to me shooting 2in spuds seems to be more fun then 1.5in.

The definition of spudcannon should include combustion, if I wanted to shoot a pneumatic I'd go get my paintball gun.

I wouldnt call this plain, there is much simpler on the site. I like it and the paint job is clean, but you severly weaken your chamber the way your screws for the spark gap are placed, great job on the successful angling of your spark gap screws, but on any future build the safest place to put them is in the couplings where it is twice as thick. nice build, add a handle or something.


EDIT: to be the first to warn you, the DWV police are gonna getcha

Yes, your probably right I should have added a coupling but was very hard to get all four gaps close enough.

Future plans: SPARK STRIP
