Reducing tablesaw dust output

[matt]

My tablesaw is now the biggest dust producer in my workshop. Currently it has no dust extraction facility at all. It's contractor style with the motor hanging out the back. I plan to enclose the back as best I can and leave cut outs to swivel the blade (and therefore the motor...) to 45 degrees. Underneath I plan to install something like below. The hose from my Trend vac will plug in to a pipe fitted high up to create a vacuum and suck out the really light dust, meanwhile heavier stuff can fall to the bottom and be cleared out via the removable front every now and again.

Any thoughts welcome...

This is similar to what you have drawn.
I was going to do this sort of thing for my saw,but boxed the sides in and put a 4" pipe in the back which seems to take most of the free dust away.
Still get a fair amount coming off the top though which will be hard to stop :roll:

There is an article in May/June edition of Fine Woodworking about dustproofing table saw's might be worth a look.

The hopper design isn't very effective.
Better to build a cowling around the blade that uses vanes to direct the blades airflow down the vacuum pipe.This can be a wooden box screwed to the trunnion to tilt and rise with the blade.
Google WIS24 the Hse page on this subject
It can be helpful to look inside a European sawbench that has the cowlings designed to meet our Emission standards, they are often very simple to replicate.
