In my current shop, I've got my downdraft table hooked up to my DC. This is a bit of overkill even with my 2 hp DC and in the new shop running a 3hp cyclone DC for a teaspoonful of dust/minute will be like killing ants with a tank.
For the new shop I'm looking for a design for a downdraft table that will incorporate a self-contained filter system. I've seen a few simple designs that use 20" x 20" furnace hepa filters and a basic window fan. Simple, cheap and - effective?
I wouldn't mind buying a small 1hp single bag unit for beneath the table. I use one on the laser for outside exhaust and it'll be plenty strong.
What have you found to work? Do you know of any design you think might fit the bill but haven't gotten around to building yourself? Money is not a factor.
Also, what do you use for a table-top grid?
I have about 30" x 72" allocated for the overall size of the station but only need about 24" x 30" for the grid area.
