Cannons And Cannon Accessories
This is such a great forum that I want to get active on it and by showing some of my efforts. I am helping a 10th grader with an AP Physics trajectory project, and decided that I needed my own version. I wanted something to launch antennas into (over) trees. My first unit was a 4' long piece of 1/2" Schedule 40 attached to a blowgun, itself attached to an old Sears 100 PSI air compressor. It will shoot a 6" long 1/2" bolt with attached string 75' in the air, easily clearing any tree on my propeerty. Pursuing greater portability, I made a series of "Carrot Crushers" (favorite ammo is peeled baby carrots from Safeway, on sale @ 4 bags for $5!) The latest is a Laser sighted unit with a Rainbird valve.
 This gun could fire a couple of shots of air from a single fill. Ammo is loaded by hand for each shot.I prefer lead slugs Max pressure during testing 20 bar. I took this gun apart pretty soon after it was finished cause I needed the parts to make a prototype shotgun. I will get threaded thick walled steel pipe& fittings to make that one however. Might try to go up to 60 bar (CO2) with that one.
 New!!

A possible idea for better mixing of gases in a combustion.
 this goes very far
 I made this cannon in about 2 hours cost me about 100$. i get it upto about 400psi and it goes about 2k.
 Nothing special here, just my first cannon :) It's a travel size tylenol bottle, pen casing, 2 thumbtacks, BBQ ignitor, Old Spice, Q-tips... rest is self explanitory ;) Expect more from me soon!

My first cannon that I built. It has twin 4" sch40 pvc chambers and dual 1" orbit sprinkler valves. The barrel is 2" sch40 pvc and measures 40" in length. I have a buddy that works for a company that does spray on bedliners for trucks so we sprayed the entire gun in Line-X not only for appearance but also for safety. Hope you all like!
 Just thought I would add mine
 thsi is my newest gun it is the spudinator cp. the barrel is 2" and about a combined length of maybe 8'. it has a modded valve except intead of the internal equalization it is external (thats what all those extra valves are for) it is spray paint not real metal. i fire 2" chuncks of wood cut from a hole cutter and cocking gun tubes.
 Small eh? fun to shoot. LEDs, Erasers, Nails, Dandelions.

My first shooter
ya this is my pnumatic ists really basic but i love it and my friends think im some kinda genious by makeing it. But im actually attributing this cannons design 100% to the geniouses on this web page
 Its a normal combustion cannon using propane and a sparker made from a disposable camera. The spark is so big that it shoots 100% of the time. I've calculated the max effective range to be around 6000ft, but there's no where open enough to go test that out. The barrel is 7.5ft long w/ a 36inch combustion chamber. It also has an internal computer fan that will exhaust the smoke/gases after a shot, and it also mixes the air and fuel before shooting...
