Radial Arm Saw Dust Collection
|The radial arm saw ... you either hate 'em
or love 'em. No one can argue that they are difficult to
connect to a dust collection system. But you can get 90%
or more of the dust with a very simple box collector.
This page describes how I did it.
||Here you can see the very simple box collector that I
built for my RAS. The box is built from aluminum sheet
metal. You could use galvanized if you preferred. This
material is sold as roof valley flashing at the home
centers. It is easily bent using pieces of scrap wood to
help define the corners. You can see the hole at the
bottom where I connected my 4" dust collection
fitting. The box corners have 3/4" flanges bent
around the corner and secured using pop rivets.
|Here you can see the DC piping connected to the
bottom of the box. I chose to mount the box to the wall
behind the saw rather than to the saw itself. The box
extends 2 - 3" below the saw table and I think it
could be improved by adding a front lip to the box up to
almost the level of the saw table. This can grab most of
the dust produced by the saw, and it's pretty cool to see
the air flow swirl the dust around and down into the pipe.
My DC is only a 650 CFM unit so bigger units should work
|I'm very pleased with the way this works. Before I
had this in place the dust simply blasted against the
wall behind the saw and ended up in a big pile behind and
under the saw where it was most difficult to get cleaned
up. By locating the box next to the saw pillar, the dust
is directed into the box even when making miter cuts.
Obviously it won't work when ripping, something I never
do on this tool anyway. This should work just as well for
miter saws too.
