First cannon [ TDC-10 ] (with videos now!!!)
I'll go ahead and post here again, that cannon design is AWESOME. I think you did a fantastic job, nice and clean too. Feel free to add some more bells and whistles like propane, but if it was my cannon I would keep it how it is -- nice, light, and easy to handle. I also like the end of the barrel how you have that fitting on there (i suspect thats for looks?) does it affect how you load potatos? I would think you wouldnt get as clean cut.. Anyhow, great work.
Looks beautiful especially for a first cannon. I'm pneumatic only at the moment since I don't want to tackle the propane meter tuning. 13 air powered devices later and I still don't have a smoking gun. I still haven't painted any of my junk 
.
I cannot beleive the size of that barrel though. Is it a tennis ball gun
cuz you would have trouble finding potatos over 2" and if memory serves 2.5" is a good tennis ball size.

That fitting doesn´t affect when i load the potatoes... i use a different mode to load, with cartridges... Look:gwoloshyn wrote:I'll go ahead and post here again, that cannon design is AWESOME.

when i told that i use cartidges u thinked i was talking about bolt action or something else ??? ^^ralphd wrote:That's it?? I think it's supposed to come back out....a little faster and louder.

Hey look at the first post, i added more videos now !
Nightshot, please use proper grammer when posting..
And if you have a dremel or a ton of sandpaper, put an inside chamfer on the barrel so when you load the potato from the cartridge it will slide in alot easier and make a much better fit. You'll be surprised how much power you can loose if you don't have a tight fit!

He's already cut the spud to shape in the cartridge, so once he pushes that into a barrel diameter thats the same as the cartridge, nothing will change. The chamfer is just there to provide a smooth "introduction" for the spud into the barrel for a clean fit..ralphd wrote:If you put the chamfer on the inside of the barrel wouldn't that compress the potato and build up too much back pressure?
Bull$hit, i get all my 2.5" pipe from homedepot, it's grey sch40 electrical conduitdaberno123 wrote:Home Depot won't sell 2.5 pipe. You'll probably have to order it online from BC Arms here
<a href="">DONT TAZE ME BRO.. DONT TAZE ME... AHHHH</a>Yea, that's definitely going to get you at least a tazer.

Yes, for a standard combustion, 2-1/2" conduit will work for a barrel. I've seen the stuff at every Home Depot I've been to. If you do get a barrel from there, and you're still muzzle-loading, do the following two things:
1.) Get a length of pipe with the bell-end still intact. This allows the ball to be loaded easier, for muzzle-loading.
2.) Get a length of 1-1/2" SCH-40 with a coupling or bell-end at the end. This will make a superior ram-rod, because it applies even pressure around the edges of the ball where it meets the pipe, allowing you to load easier. Just a regular broom-stick will compress the ball in one spot, making it jam up frequently during loading.
If you ever build a pneumatic or other high-powered cannon, make sure you use pressure-rated pipe for the barrel, and not conduit. Also, if you use any long lengths of the pipe for a barrel, make sure it's supported properly. Conduit is more rigid than regular PVC, but it's also a little more brittle.

All materials which *should* be used for making combustions can withstand a full closed-chamber ignition, even DWV once or twice, (unless subjected to shock or physically damaged).ralphd wrote: If you put the chamfer on the inside of the barrel wouldn't that compress the potato and build up too much back pressure?
thanks... I am brazilian but i live in japan.... and I am using a deodorant spray now ....gwoloshyn wrote:Haha, nice videos man. Where do you live?
Thats a really fine cannon you have there.. What are you using for propellant?
