downdraft table

I’ve worked in many a professional shop, seen many a homemade down draft table and with rare exceptions, they did anything but suck dust.

I recently used one that did work but it wasnt cheap to make. 36” x 60”. 1/2” baltic birch top covered in 1/8” rubber, 1/4” conical holes on 1” center to center. Under that was 6” of open space with three firmly fitting furnace type filters and under each filter was an explosion proof motor driving a super sonic squirrel fan. It was also 220 V.

they used the “candle test” to determine when the hole dia., were big enough. I didnt say anything but my guess…..............they could of bought one for less $$$$.

I agreed with Moron on the “conical holes” or also known “counter sink” holes. They work better than straight holes.

I saw this on Sawmill Creek yesterday: http://www.dreamgarage.com/workshops/featured/shop-tyme
Page through the pictures, he has a combo downdraft/outfeed table on his tableasw. It looks like he has it connected to his cyclone dust collection system, but I’m sure it would work modified with squirrel cage fan.

I built mine with a 1/4 inch perferated masinaite with a copple of 3/4 inch 1×4 under neath I use it for sanding table It takes a way all the dust from sanding. works great It also takes out dust that gets in the air.
