its comming. im headed to the dump tomorrow and il see if i cant find some bike gears and chain for a proper elevation adjustment. Unfortunately my 12v compressor went up in flames after repeated 150 psi shots, so im in the market for one of those too

Just an update here Cannon kicks butt!! still have to get me some bike gears and chain but were putting manderain oranges 250-300 meters. also moddified the breach to reduce dead space and better air flow

here on Vancouver island we can't even open the local mountain for skiing... one of the dryest and mildest winters we've had in 50 years...

EXACT same problem with out 70's era 115 evinrude.... got us stranded for a few hours... it will run intermittently but will crap out most of the time when there is a load on the engine... basically its weird.

its just gas going down a tube so its the same principal... if you want a quieter launcher go with a longer barrel. if your really concerned about noise, you shouldnt be. you can be as loud as you want in the woods 8)

Thats the best thing I've seen in a long time!!! then again all ive done lately is worked... had to trade spuds for spud wrenches

Something more along the lines of this (posted below). I prefer the more mechanical approach with ropes and stuff.

Biged, LOVE the mortar, please tell me its functional :D thanks Zeus, but i dont think I could bring myself to use a turn buckle... Here's a hint about my capabilities, CWB qualified Welder/Fabricator with home access to welder (steel and aluminium), basic grinder, Oxy fuel torches and half a drill ...

my only advice is lots of practice to get it dialed in and maybe one of those range finders for golf and set up some 6 foot tall targets down range.

I hate to go fishing but Im looking for ideas on an elevation adjustment system for the cannon/carriage posted below

yeah... mines a little bigger... I test fired it without the carriage yesterday and go knocked on my ass. 2''pvc x3' chamber and 2''x6' barrel with a 1'' valve, same configuration with the breach too. luckily i work in a welding/fab shop and have access to a press brake and all sorts of cool stuff w...

awesome howitzer there im building a slightly larger piece with a modded 1" valve and was curious how the recoil was and if a recoil system might be considered?

Also, even as a Welder Fabricator i still find Oxy fuel guns terrifying.... it can be done safely but its still really unsettling.

I have no idea how you found that page, google wasn't kind to me. Basically it'd be an awesome main valve for a large cannon... Apperently it's rated for 400psi

I have a very vague idea of what I recently aquired (for free). All I know is that it's a 2" pressure control valve made by singer and its freaking heavy.... From what I understand its essential a really big sprinkler type valve (diaphragm valve). Any ideas?
