Couple months ago I built a DC using my 16 gallon Rigid shop vac and two 5 gallon pails that fit together. The idea came of the web. It separates the larger chips quit well but fine dust still gets into the shop vac and plugs the filter before long. So today I added the Thien baffle just below the inlet post.
Actually I've just added a central vac that is vented outside shop so the Rigid shop vac won't be used for now. Problem with the central vac though it doesn't have the same power. Next step is to change the Rigid vac to vent outside.
comments anyone?
