J. Phil Thien's Projects

Hey fellas. Piggy backing off this post.... I have a top hat over a home depot bucket and one over a square box that I built. I noticed the box will fill 3/4 full before dusts starts going to into the shop vac whereas the bucket fills about a third before it goes into the shopvac. I put a plexiglass window in both and I see more turbulence in the bucket where as the dust in the box is more settled. Is the box better in keeping the dust down? Your expert is appreciated
