cannon ball mold

[thinwater]

I made this on my old Bridgeport at home. It makes 4 .750 rond balls each pour.

Now I just need to make a cannon to shoot them in.

I love you guys...
I've wanted a cannon for over 40 years. When I was 5-6 years old, I used to drill out big bolts, fill with firecracker powder and a lead ball I hammered round from a piece of tireweight.

I know what you mean when I was a kid I would cut open dads shotgun shells to get powder for a 1/2 in water pipe cannon amazing all my fingers survived to adult hood you can see the first firing of this barrel on youtube at

Very nice work.

I made one like it but with a bore to shoot tennis balls filled with concrete. The barrel/tube weighed 90 lbs alone. I used one .22 Stinger box heaping full of 2F black powder to fire it. I got the super sonic crack with this load. The fireball was huge. I have it on video but it is 20 megs and I cant post it anywhere.

How was the recoil on a tennisball full of concrete?

would like to check out that video  .  have you tried to upload it to youtube - it will convert it to a flv (flash video) and then others can view it.  if you are not familiar w/ that, are you familiar w/ ftp?  i can create you a username/password to one of my ftp servers and and then convert it to a smaller size for you and then get it back to you or host it on firearmsfiles if you want.  lmk your computer knowledge and i can make a short video of how to install and work w/ a ftp client if you want.

The tube was sitting on a few boat cusions to give it the correct elevation. It jumped up at the front about 10 inches and the whole thing went back about another 12 inches. Not to bad, but when you consider it weighed 90 lbs that was a lot of recoil.

Just wondering thinwater sounds like you might be one of those guys who have a boat to spend his grocery money on. that plus testing a cannon barrel on boat cushions. my wife and I have a 72 model 35 morgan sail boat we restored a few years ago  enjoy all your postings and learn a lot keep up the good work
