Been experimenting (crudly) and came up with this so-far; works pretty good.
Tested it out with some pine and maple - 60, 220 and 400 grit (just testing ;) and havnt power sanded yet) and there are no visible dust particles in the air/light (still gonna pick up a 1/2 mask soon) but this is good that there is no sanding dust laying every where.
Using 60 grit on the pine, i took out a 1/16 - 3/32 thick, 2" dim collar off a piece and nothing was floating in the air.
Sorry dont have a pic of the inside filter, its all taped up for now, but its nasty with dust.

Two 8" line duct fans (http://www.lowes.com/pd_185010-1061-DB208_?PL=1&productId=3089847), one 14x24" filter, roofing-boot and shop-vac.
The top box is make from 1/8" paneling, the 8" fans are mounted to 1/2 plywood.
Right now its all held together with screws, the tape is just to stop air leakage.
Black roofing-boot held on with a quick-release-clamp, shop-vac hooked to it by a coupler pushed through the boots rubber seal.
The top - front panel was gonna be a second filter (it may still) to get max air flow, specially when the filter starts to get clogged.
How its constructed, i can spin something 11.5" dia. with no obstruction - full lenth of bed (the back 20" half of the piece would not be under the dust hood)
The shop-vac is on the other side of the wall, which is nice, its not loud at all.
Still have more playing to do (making it smaller for one).
The roof-boot is being held on with quick-release clamps (so i can slide/move it easy), might change that to some kind of "slot, sliding thing (top and bottom)" or trash the boot idea and bend some round duct work and rig a 4" outlet (in case i end up with one of them small $80 HF potable DC ) with a reducer for the shop-vac hose.
All and all, im pretty happy with the performance, specially since its all made from left over stuff from when i built my addition (except for the two 8" fans and filter). Its not heave at all, maybe 20lbs, but it is awkward to move around - and storage when not using is gonna be a pain.
Dont know how long the 8" fans will last with all the fine dust being pulled through them - gonna try and clean them after each use with the shop-vac.
any idea's or thought's, please post :)
