New barrel advice

I am making a silenced barrel. My chamber is 4" SCH40 x 17" long. I currently have a 1.5:1 C:B: ratio with a 43" long, 2" SCH40 barrel, and its LOUD. I was thinking about lengthening the barrel to 60", making it closer to 1:1 and having the last 17" of barrel the silenced part, using 4" SCH40 as the...

PVC isn't tempered glass... Last half a dozen pvc failures I've seen posted here consisted of fairly sizeable bits. I wouldn't run out a generalisation on hearing of one incident. But it would be nice to see a deliberate cellular core ABS failure. Might require a hybrid mix or perhaps a pneumatic o...

They assumed it didn't, this implies noone has ever had an ABS failure? Or they are that rare lol. Dammit, I want ABS failure stories! Someone back on Spudtech had an ABS failure. It didn't just "crack" though, a big chunk of pipe blew off. Crazy, sounds intense. If I have a failure with my cellcor...

I'm a mechanical designer with the latest Solidworks, and started designing my cannon using it, and said screw it. All I need is Spudtool! For something so simple its a waste of time to reverse engineer friggin fittings. if you want, go to http://www.3dcontentcentral.com. Many of this stuff has been...

Wicked thought for ammo

OK, i'm probly not the first to think about this, but immagine using like a well sealed wooden or plastic peg as a wadding, and dropping an arrow (bow and arrow type) ontop of it. That would totally sail. I wonder if it would be faster than using an actual bow. Like, if the velocity of the gasses ex...

I have a little camera with battery onboard its small and all self contained so it will work. Its been lying around for ages so if I don't find it its not a big deal. As long as the video records. I figure I could put some wadding underneath it to prevent the lense from getting burned upon firing. I...

Camera projectile

OK, so I have a little wireless camera for my RC helicopter that im thinking about stuffing inside a small model rocket and launching it out of my spudder. Camera would be facing downward and mounted in the body of the rocket. The rocket would have fins of course so it ought to fly straight up. I th...
