Combustion Cannon Modifications

Unread postAuthor: heavymetalsarge » Fri Jan 12, 2007 12:56 pm

I'd just like to see what other people did to their spud cannons
for example I:
wrapped my camber in high stress nylon rope to prevent the camber from fragmenting in your face if it does explode
and I fashioned a rifle style stock and mounted by BBQ lighter in it.


I just want to know for my future projects

Consider me a noob but how do these camber fans work?

if it doesn't involve a loud bang it isn't powerful enough

By mixing the fuel and air better those causing the fuel to burn faster resulting in better performance. http://www.spudfiles.com/spud_wiki/ this link has loads of info.

Other good combustion modifications:

METERED PROPANE INJECTION - Best mod ever
Cool handles
Breech-loading setup
Over/under barrel configuration (shorter overall launcher)
Spark strip (much better than screws for electrodes)
Already been mentioned, but a chamber fan and/or high voltage ignition source (stun gun, flyback circuit, camera flash with step-up)
Shoulder pad (reduces kick when firing heavy projectiles)
Muzzle/breech knife (sharpen barrel with a file on whichever end you insert potatoes into - makes loading much easier)

Etc....

I have no idea why I just wasted my time typing this out.

Peace,
Pete Zaria.
