Dust Collection Question - MVWoodworks - 10-29-2019
Hi All,
I have a cabinet saw and a 650CFM dust collector. There has always been some amount of saw dust that came out of the spaces between the table top and the cabinet. However, since I added a Thien Baffle to the system, I'm getting a lot of saw dust coming out of those spaces.
Is this normal? Is there something I can do to stop it?
Thx, Jeff

I'll take a stab. You have a minimal (I think) DC and adding the separator reduced the flow further. Separators are always a good thing, but they do introduce some drag on the overall system...that is the nature of the beast. The best way to reduce the amount of dust escaping the cabinet would be to get a larger collector (if my assumption on the size of yours is correct).

I stuffed pink fiberglass wall insulation into the holes under my saw. Works quite well.

I've always had a separator, just upgraded to the Thein design. Also converted from ribbed hose to smooth-inside hose.

Interesting. I thought the holes were necessary for air to flow through the cabinet?

Not my 1022 Griz. There's enough holes by the blade insert, the tilt knob, the height knob......

Yup, I used left over Kaizen Foam on my Jet Contractors saw ... also filled the hole at the front where the height adjustment wheel rotates during angled cuts.
There's enough "leakage" elsewhere to allow proper draw.

They are, but if dust is coming out of a hole, there isn't enough air flowing into that hole, so plug or guard it.
But it sounds like you really need a larger DC system, I'm sorry to say. It takes a LOT of air movement to capture dust in a TS without some escaping, and that doesn't even include a blade guard with DC port.
Edit: Oh, and that 650 cfm is probably moving around 300 cfm with bags and hose and machine port attached.
