I have a chance to pick up a really old, but functional Orbit Thermo Vacuum Forming machine. It was made in New Mexico in the 1960s I understand. It's something like 400 pounds. I can get it for next to nothing. Are they any good?
It's sitting in an old warehouse in a neighboring State. The guy would probably let me have it for next to nothing ($100 or so) if I just got it out of there. It's made by a company called Orbit out of New Mexico. I'm told it was made in the 1960's. I believe it was used to make plastic cafeteria trays. I understand that it can handle something like 20 by 23 inches.
If I were going to buy this I would go to their location, with some pre-cut sheets of plastic and test it out, if they are not willing to let you to do that then don't bother, something is obviously wrong with it.
As-is condition might mean that it doesn't work at all, and you might have to buy all new parts just to make it work, and all that trouble wouldn't be worth it.
