Looks good! I would also add another gap to the center. More burn time in spherical mode baby!

I was actually fixing to get some 3" cam-locks for my next cannon. It's easier to breech load (largest size that will pass through a 2" cam-lock is 1-1/4" pipe). Can a 2-1/2" pipe pass though a 3" cam-lock?
Thank ya very much! I had a little trouble getting the pipe to fit, so i used a belt sander and rotated the pipe around and shaved it down enough to get a nice fit. And I may be able to squeeze 4 sparks outta the bbq ignitor, but we'll see.

I appreciate the kind words :)


Ah the ball valve vent. I had thought about it, and decided if I got tired enough of unscrewing the cap, take a 4" male thread adapter, 4x2" bushing, and a 2" valve and be in business. So who knows? I have a feeing quite a few more things will be added... :D

Yes! Beautifully so....the 3"male camlock anyway and at least on my model camlock. If not it will be very close and you can easily sand it down some.

Ok so I shot Rebel Yell for the first time with a tennis ball in my backyard. Two of my uncles came over to see it and I just had to show it off. At a range of 5', I hit a milk jug full of water, big bang, big water splash, and everyone was happy :D
Its not much, but its the first of many damage pictures to come...

Alright yall, I finally have some pictures. At work today, one of our secretarys came in the shop to talk wit my supervisor. As I was walking by my super said "and theres our little pyro outlaw" After a short explanation of my cannons, te secretary wanted to see a demonstration. So I wrapped a 3/4 bolt in duct tape and rounded up the guys.

My super told me to shoot at our storage building, thinking it would bounce off like the potatos. Not so much. That sucker came out the barrel and went through the wall of the building like it was nothing. We were all crying we were laughing so hard. And I didnt get in trouble :D

So we stepped it up. Theres this old van sitting behind the storage building we've been eyeing for awhile and tonight was the night. I put the duct tape ball back in and squeezed one off at the van. Quite an ipressive dent, but no penetration (gotta hate no penetration) so I rloaded and put another 3/4 bolt down the barrel in front of the duct tape. Boom. Penetration acheived.

I love my job.

And here are the pictures of the damage and of the modifications to the gun.

Sweet damage there bigsauce! Nice long barrel there. You should build a sleeved SDR 21 golfball barrel for that thing.
