Cannons And Cannon Accessories
All copper gun with barrel sealing piston. Barrel length approx: 1.8 meters. cal. 18mm
 Here is my buddy Leroy holding my biggest cannon. Its a 5'X4" chamber through a supah valve into a SCH80 2" rifled 5' long barrel. Its Evil.
 this is my first pnumatic it has a 2x24 chamber and a 3/4 x 25 barrel i got arrested for it
 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!!

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!
