My original 24"x32" oven was plenty hot on ... |

Wow, that is a really nice machine you've built, and one heck of a bargain for a Proto 2000 vac table!
Good luck with the sale!

It sounds like you should be in good shape for pulling the armor with that super fast vac pump. Biker scout and snowtrooper armor have nice flowing shapes that are easy to pull on a vac table.

The Gast 1065 pump looks like a reasonable price considering it comes with a motor as well, but that paint color - blech!

Hi Lou,
The pump looks very similar to the ones recommended by other folks in the past. The power requirements look good - 110 volts AC, so no need to setup a special 220 volt circuit

Nice video and beautiful work on building the Protoform vac table!
Can you provide some additional information about the digital temperature controls for the ceramic heaters?
