I have a requirement to create 2 plastic hemispheres - 14" and 13" diameter.
I'm new to vacuum forming, although I've been happily CNC milling and laser cutting for some time.
My question is how much plastic (in X and Y) would be required to form the two hemisphere?
Low detail, so 1/16" thickness plastic would probably work OK?
I'll be making the "plugs" using CNC egg-crate process, filled with fine plaster.
All advice gratefully received.
Thanks,
Steve
