Stan I think your right I'll put my shop vac air purifier down on my work bench next time I'm sanding to see if that helps. Thanks
If I`m getting this right, your using the 1 1/2" hose on your vacum ?
I would definately use the 2 1/2" if you have it.
And did you say you did not have a bottom on it?
Sealing the bottom would concentrate the suction to the box.
You did not mention how many holes and what size you used?
Since the vacum has good velocity but low volume, I really have no clue how many holes of what size it would handle. I know my Bt3100 , router table and CMS work pretty well with the 2 1/2 on my bigger vacum, the small one I have never hooked to a machine yet. I only use it to clean benches.
Don`t give up on this idea too soon, you may have to go back to the drawingboard a few times. But it is a worthy project to pursue.
After gagging and coughing up MDf dust for a week, I`m regretting not getting my sanding table done more quickly.
I took the 1/4" pegboard holes out to 1/2" and countersunk them.
I may have to go to 3/4", some guys using the HVAC blowers report whistling with not enough or too small holes.
