[TheForge] 8" hemispheres, shameless plug

[Jay Hayes]

Don,

I have a machine that does doming. It will not do a complete hemisphere 
but will dish a fairly deep bowl. I would have to make a set of dies to 
form the size you need, but the tooling is fairly easy to make. It is 
not a problem to dish 16 or 14 ga.
