Ralph, if you have read all of the posts by me regarding the vacuum hold down, your questions will be answered. How I use it is, I cut a piece of plastic to fit the entire fixture and turn on the vacuum. It pulls 2 lbs. per square inch, so, 8" by 32" =256 sq. in. and 512 lbs. total pressure, enough to hold the plastic rigidly for cutting. I use a drag knife in my router and the cutter cuts almost through the plastic and I remove the parts by bending the plastic. The plastic is about .040 inches thick. Thanks for your interest. Bob.
