Bringing out the big guns.
I don't think I'll need a 6" diameter vacuum drum very often but every once in a while I'm sure it will come in handy. I built this one last night so I could finish the bottom of the hollow form I've been working on for the past week. The drum is a 5" long piece of 6" diameter PVC from the local Lowes. The mounting block is a drilled and tapped piece of Persimmon I got at the 2011 DWR.
The piece was sanded with 150 grit before it was turned around and mounted on the vacuum chuck. I wasn't able to get a good vacuum because of cracks and voids in the piece but because of the surface area involved (28 square inches) even a couple of pounds of suction can hold a piece sufficiently for light cuts and finish work.
The bottom of the piece with the tenon removed and sanded to 150 grit. I need to continue going through all the grits and then apply my finish.
