My bleeder board was getting pretty thin so I decided to to replace it. Found more saw dust under it than I could believe.
It was time to re-do the table. I surfaced the plenum. Was out about .025". Dug out my Allstar gasket material I bought about 2 months back and cut a channel around the outside edge and in between the 5 zones. Squeezed the gasket (no glue) into the channels and put a new bleeder board down. The new board had to be lowered down in the right place because it would not slide on the gasket. Surfaced both sides of the board and ran a small job.
What a big difference. With no material on the bleeder I get no gauge movement with the blower turned on. Adding a sheet of melamine the gauge goes to about 14" and just starts popping the safety relief valve. Big improvement.
I do not have any glue or screws holding the bleeder down and I do not see any warping of the bleeder after 2 re-surfaces.
I would highly recommend a gasket under your bleeder. It makes a big difference in holding power.
