So I slotted a sheet of that pvc for the vacuum table. Could not get a vacuum with it, it bleeds as bad as mdf, the inside is real soft so maybe it is really a pvc foam sheet, H D is not trust worthy. Anyway I painted one slot with elmers glue and connected the vacuum system to that one slot and pulled a 29 inch vacuum. So I painted the slots with that rubberized paint to see it that will seal the slots. I’ll see tomorow. What a pain… but I have the pump rebuilt, a vacuum gauge, a shut off valve and a filtering jar all in a nice little package. One step at a time, usually backwards or into a hole but maybe we can call it progress. Jude
