the top layers of the vacuum table (the templates) will get a coat or two of shellac, thanks for the thinking about this. Your explanation of the pvc sheet is right on. Not the way they discribe it but oh well. There is appearantly a real solid pvc sheet called grey pvc sheet that is solid but over $300 a sheet (on the shopbot forum under pvc vacuum table). So oh well to that also. I enjoy yourinsights, very informative on many subjects, Appreciate it, thanks again, Jude
Here’s an interesting thought about the vacuum table itself, JB vacuum pump 85c (35 yrs old) pulls 4 cfm and the slots with a 1/8" air gap between the surface and the board (thickness of sealing tape) is 30 cubic inches, That should pull down in less than a second. Will that be the case, we’ll see.
