Little British style mortar

[Dresden]

I made this pattern about 30 years ago, I was going to get a price from my local bronze foundry in St Paul

[size=78%], the core is golf ball size, and it should support a 2.5 inch bore.[/size]

I was going to bore one for the available plastic ball shells available from fireworks companies.

I do not intend to offer castings for sale

I think it would depend on what the cost is, also if you are going to offer these in any quanity you should become a sponser.....

Gary,
What part of "boring it" are you having a hassle with?

Depending on the size of the lathe available, reverse two jaws of a 4 jaw and grab the trunnions by the ends on the first step of the jaws the other jaws grab the barrel.  I just may go to a surplus tool company here and pick up a 2" plus rill and radius grind the end for a nice bore and radius over the powder chamber.
