Topic tags/keywords: question

I’m wondering if anyone has ideas about improving the dust collection from my table saw. It is a General International cabinet saw which I have hooked up to a 1.5HP DC. I still get a lot of dust thrown from the blade; the DC port at the back of the cabinet doesn’t seem to help this at all. I’ve seen the over-arm blade shroud DC systems, but my budget and room in the shop won’t allow it. I recently read an article on FWW that talked about sealing the gaps between the table saw top and the cabinet with expanding foam and using magnet panels to seal the gaps around blade angle crank.
Anyone else do this and has it improved the DC from the TS?

I ‘ve tried to improve the dust collection on my Crafstman TS and I have come to the conclusion that you pretty well need an overhead DC of some kind to get the majority of the dust. I’ve plugged and sealed gaps everywhere I can without actually freezing my saw into one height at 90 degrees LOL! and capture a lot of the dust (far more than without it as is proven when I neglect to move the DC hose from the BS to the TS :-) but there is lot thrown up by the blade…I don’t think I can get enough flow of air over the table from underneath to capture the stuff an overhead DC would capture easily. Space and budget are my problem as well, that I I hope to replace my TS in the not too distant future.

zero clearance inserts help a lot.

Greetings Rob,

I agree with Russ on the zero clearance inserts… they do help a lot, but I’ve found a couple of other
options you can try also. First, tape over any holes in the cabinet, and around the top where the top meets the cabinet (oh…’ve already done that). But the biggest thing I’ve found that helps is to use a 24-30

or so ripping blade with deep gullets on it.. The deeper gullets will throw the dust back into the saw better than say a 60-80 tooth blade, and keeps a lot of it off the top and blowing back into your face…Using a good ripping blade with deep gullets will help, but won’t eliminate the problem altogether…but it sure helps….
I never use a 60-80 tooth blade unless it’s to rip melimene or laminant…I use the WWII blades, also…

ShopNotes issue 103 has a over the blade guard/dust collector that attaches to the fence, thats good for 90 degree cuts. I also seen somewhere here where a LJ enclosed the complete back of his contractors saw and still be able to change degrees of the blade without it interfering with the motor swing.
