I built this bench top down draft table for sanding finish work it has a port for my shop vac hose and a waste gate to hook up the palm sander on a small hose ,the peg board works real good to suck all the fine dust into my dust cyclone that I built from a street cone. I can sand with or without the palm sander and get all the dust that would normally get in the air sucked into the down draft table. I have tested this on several kinds of wood and it has performed perfectly on all You can watch my vid click the link. Thanks for looking

There’s no way that a shop vac or 2 1/4 inch hose can provide a enough suction for both your table and sander.

Assuming all the outside holes are blocked by the supports under the pegboard (Giving you the benefit of the doubt) the combined area of the remaining quarter inch diameter holes would be over 10.59 square inches. The area of the shop vac hose is under 4 inches. The suction of the hose to your sander after the down draft box would be negligible. I would recommend a dust collector with a 4 inch duct (12.56 square inch area) going to the down draft box and a dedicated shop vac for your sander.

Patrick, how does this work for you? I would think square inches of the hose vs. holes in the top would be irrelevant as long as the top value was larger than the hose size. The cubic feet per minute, CFM, of the air movement from the vacuum would be more important if I’m looking at this correctly. I am thinking of building a down draft table and have been figuring the amount of air movement would be more important than the size or number of holes in the top. I figured this could be regulated by placing flat pieces over excess holes to create greater air movement where it was needed. Of course the project will also be covering some of the top area as well.
