Thread: Dust extraction from a Table Saw

This is what I did, starting here. Made quite a difference but there was still visible dust.

Drawing air from the cabinet can't be done unless there are sufficient opening in the cabinet to replace that air. If the openings are not present the air speed falls and the saw dust accumulates. Trying to draw air through the blade opening will not work, as the timber is pushed through the blade the air entry to the cabinet is choked off, the fact is it was unlikely to supply the air before timber was pushed through it anyway. The openings have to be in the cabinet, on my own saw I cut a new port into the cabinet and left to original port open to supply all the air. In just about all cases there will be some build up in the cabinet to perhaps the height of the extraction port and generally it does not get any higher.

The overhead part is solvable in a couple of different ways. A brush strip can be attached to the over head guard and it covers and seals the are between the solid guard and the table saw top surface. The timber being cut will push the brush guard as needed and due to the brushes not having an airtight seal this allows air to drawn through but at the same time it stops most of the airborne debris getting loose.

The second way is to buy one that works like this....

Dust Collection

Works well and is easy to remove. The only issue is there are usually long delays from the supplier but that is normal and he always delivers.

Given the right approach the TS (cabinet style) is generally fairly easy to put dust control on unlike the band saw and mitre saw.

Edit, I found a photo...

Thanks Mini great info and mic-d for your adventures in dust control well done.

My 2 cents worth if it helps.

Still not perfect but better than it was.

Excellent I was hoping for some idea on how to modify the existing blade guard as I move my saw around a bit so an overhead is not workable.
Do you find the dust control from in front of the blade sufficient? The Shark system looks good especially being able to see the cut but a fix like yours will suit me just fine I think and I do need to modify the splitter so it doesn't need removing when using a sled.

Many thanks

I have yet to build an overhead guard/collector for myself but I think most suffer due to lack of air flow. It stands to reason that if you are pulling for example 500 cfm through a duct or to put it in another way the duct and DE can do it then you must have some way of that air getting into the guard/collector AT ALL TIMES. By that I mean if a piece of timber is pushed under it and begins to close off air entry then there must be some other method of getting the air in. If you only allow 100 cfm in then that is all that is going to be extracted and DE performance will reflect the air flow being allowed.

My saw has 2 dust ports.
One (100 MM) from the cabinet and one (40 mm) from the Suva Guard.
Dust is still coming from the blade but not in a great amount.
Overall it works pretty well.

With only 100 and 40 mm ports available it is almost certain that invisible dust will be spraying everywhere. A 150 mm duct on the cabinet (with the cabinet well vented so that it does not restrict air flow too much) and a 100 mm on the overhead guard would be a minimum to capture most of the fine dust coming from a table saw. This of course assumes you dusty has at least 150 mm ducting and generates a decent overall air flow at the impeller.
