I am using a Rockler portable dust collecter on a Ridgid granite topped table saw. Its connected with a 21 section of flexible hose. What kind of results can I expect? So I still get tons of dust in the cabinet and very little dust is pulled out. Is this normal? I know I could probably seal up some of the holes in the saw, would this help the performance?

I should note that this is my first dust collection experience and maybe this is normal for tons of dust to pile up and then the collector just takes out the extra.

Dust collection is based on the movement of air. The farther the dust collector is away from where the dust is, the higher the CFM’s need to be. I have a 1500 CFM dust collector and the longest hose I use is 10 feet. The length of hose from saw to collector, I think, is what your problem is.

A 1HP DC pulling through 21’ of ribbed hose? Yeah sounds about right… You either need a bigger DC, or a LOT less hose.

Yes. Seal up the holes that you can. Try some tests. Use 2” wide plastic sealing box tape (it is easier to remove later than duct tape) or duct tape if that is what you have. I am not sure of your particular saw, but typically the hole for the blade up/down is curved shaped so you can tilt. This can be a very big hole. Generally the only hole that you want to draw from is the slit for the blade. It is possible to starve the intake, but I doubt you are having that problem.

And shorten the hose. At least for a test.

Test, try, test. (It’s free.)

to maximize what you’ve got now, put the DC right behind the TS, and use 3-5ft of hose, nothing longer. also open the TS cabinet, and seal off any cracks in the cabinet lower and upper parts. you’ll still have some openings where the handwheels are, so don’t worry about over sealing it.

other than that – even with a Jet 1100 DC I still have dust left in the cabinet of the Ridgid TS on the sides – but whatever is inline with the DC port stays clean.

Curiously, I just finished ripping about 25 board feet of hard maple (using a 24T rip blade). I noticed a much larger accumulation of dust than normal on the floor and table of the saw. Actually, the dust was in the form of strands rather than “dust” per se. A rip blade of course has deeper gullets and cuts much like a chisel.

When doing cross cuts, either with a combo or a crosscut blade, the dust is finer, and the DC sucks it up more efficiently. It is of course the fine dust that can become airborne that we are most interested in capturing

FWIW, it should be clarified. Dust above the table, and below are two different things. A zero clearance throat plate in particular keeps a great deal of the dust above the table, a guard with a dust port like a Shark Guard or other aftermarket guard will go a LONG way to keeping your shop air dust free. HOWEVER, your 1HP DC doesn’t have enough grunt to pull from both below, AND above the table. My 2HP would really be stretched to do that. I use a 2HP DC plus a shop vac, the DC gets below the table, the shop vac gets above the table…

What all of the above said. What MedicKen, Miket, and dbhost said, too. Basically what everybody said.. That’s what I would say, if I had said it, but no need to say it… already been said. Somebody say something?
