- General George S. Patton (1885-1945)
In particular I needed to seal up my box, it was clear that there were air leaks and they were have an effect. Second I was using my old shop vac which even back in 2009 was old and worn down, I expect that I would see better results now with new equipment that I now have.
I know where the box is but not the peg board pieces so I might just pull this out again and seal the box and make new inserts and have a go with my newer shop vac and see how that goes.
The thread explaining what I did is here:

You might not get the same amount of theoretical holding power using the DC versus a vacuum, but if the table has any size I bet it would work just fine. With a full vacuum, you get 14.7 PSI of pressure, which works out to over a ton per square foot (14.7 PSI x 144 in^2). While the DC wouldn't pull near full vacuum, you make up for it in size; for instance if it only pulled 1 PSI, you'd still have 144 PSF.

A dust collector and a shop vac are basically the same thing. A motor and an impeller. The only difference is air flow. The air is what puts the load on the motor. If you reduce the amount of air the impeller is moving the load on the motor is reduce and the motor speeds up. That is why when you block the hose on your shop vac the noise increases. It is not working harder it is running faster because the load is reduced. If you run a motor with an impeller in a vacuum there is no load on the motor.Hobbyman2 wrote:Years ago in the shop we had a table that had small holes in it maybe 1/16 in or so dia , on the under side there was flat duct work with a vacuum connected to it , when you turned on the vacuum the table actually held down the work project ,flip the reverse switch and the sheet would float like a air hickey table , just wondering if this could adversely effect the motor on a dust collector,, or if any one has tried this .
As long as the motor is rated continuous duty it should actually help the motor.
