Thanks for the compliments. The Shopvac had plenty of power to do the job. The plastic I used was 15"x15" but my plug and base was at least 6" tall so I had to stretch the plastic quite a bit and it sucked it down fine. I tried 325 then 350 and finally went with 400 degrees. @ 400 the plastics started to distort and slight sag after maybe 2-3 minutes. I immediately pulled it out and threw it over the plug and machine. It was a blast just doing it. It sure opens the hobby up for a lot of scratch building. I'm glad I tried it. I made my machine out of a desk top shelf that I was going to throw out.

God Bless!
