[TheForge] 8" hemispheres, shameless plug

[Jay Hayes]

Buddy,

The machine has about a four foot throat and a 1/4" capacity so it can 
handle big parts. Large diameter parts formed with a deep dished dome 
can be a bear to handle but are often doable. Actually, some larger 
diameter parts are in few ways easier to form than smaller parts. I have 
domed six foot diameter tank heads in one piece and ten foot diameter 
heads in two pieces. I also have a bunch of other large machines for 
various types of plate and sheet forming. My CNC plasma will cut blanks 
up to 72" x 126" in one setup and I can roll or bend 1/4" plate eight 
feet long. Feel free to email or call me about your project.
