Thread: sealing up a cabinet table saw

If you close off too much of the air entering the cabinet all you'll do is restrict the flow due to a lack of make up air. If it's working ok you won't make it better by restricting the incoming air.

Aldav, I understand that, just wondering though that if I open up the (motor) door vents this would create a more cross flow effect.

If you're achieving full flow through those 2 x 4" outlets you'll be getting plenty of airflow past the motor. You haven't been having overheating problems with the motor, have you? If not, I'd leave good enough alone. As far as a cross flow effect is concerned it would seem from what you've said that the scavenging effect from the cabinet is very good as is.

fair point, hadnt actually thought that far, 'if it works and dont break, leave it alone'. let you know the results down the track.

You could try propping the motor door open a little at a time and see what the effects are. When you get to a point where the collection in the cabinet starts to fall off you can back track a bit to where it is best and measure the area of the opening. Then you can open the louvers or other parts of the cabinet you think is best.
