Default Radial Arm Saw Dust Collection

Radial Arm Saw Dust Collection

I know that Radial Arm saws are not in favor these days , but what can I say I cut my teeth on these saws and have my old Craftsman set up for cross cutting. I use it for just that purpose, no angles or ripping. The saw is known for making lots of saw dust and it piles up in the most inconvenient place, behind the saw.

I rigged up a dust collection box behind the blade that the blade is buried in when not in use. The dust collector 6" duct is attached to the top of the box, the front of the box is the fence. Then I made a ZC insert for the blade that slides in and out of the table to the front with a dado under where the saw blade cuts that extends back to the DC box. This system works 98% to remove the saw dust, and the ZC is replaceable.

Nick this works very well there is no sawdust at all that comes out of the blade guard outlet.
The DC is pulling air into the length of the saw cut and thru the dado which is open ended, I put additions holes in the end of the box to increase the air flow.

Nice solution. Don't have one, but I like the approach.

The more I do, the less I accomplish.

Those pictures bring a lot of bad memories back. My Craftsman RAS was a real pain to keep adjusted and very hard to adjust. You are right about it being good about spraying dust everywhere. I am so happy yours is a better saw than what I had and you solved the dust problem.

Measure once cut twice and it's still to short.

Good point, Herb...I normally put the vacuum on the blade guard connection...works ok but it misses what the blade spits before the guard captures it. Your solution will take care of that. I need a new table anyway...LOL...

I have been using a Craftsman Radial Arm Saw for years and hardly ever have to make adjustments. It is very accurate on 90 degree cross cuts and can manage wider boards that the Dewalt chop saw. I have a hood behind the blade and dust hose on the blade guard. I think that Herb’s method is more effective. By the way I just sold a friends Craftsman Electronic RAS for $350 Was totally suprised I got the price, but it included a cabinet, extra blade and a replacement blade guard. There are still a few people besides Herb and I that like the RAS!

I went a little different in my RAS dust collection and it made a remarkable difference. Whereas before I would have sawdust everywhere, particularly on the wall behind the saw and all over the floor and work surface, I have had very little (if any) accumulation since building the collector, often requiring just an occasional simple brushing from the front of the fence.

I use my saw for both crosscutting and miter cuts so needed to collect from different directions which required a more open concept. The shield is a few pieces of plywood glued and brad-nailed together and fastened to the upright support. I fastened an adapter at the bottom which is connected to a 2hp Grizzly G0548Z dust collector.

Please disregard the blade that is on the saw and it looks pretty rough (which it is). When processing reclaimed lumber, I will often clean and remove rotted, nail-filled or otherwise unusable ends and sections, and I use an old worn blade in the event I miss any nails or other items that would cause damage to a more expensive blade.

The dado cut beneath the table on your unit is quite impressive Herb, and keeping the sawdust contained like that would have definite advantages. I still favor the RAS in my shop also and it plays an active role in much of my workings.

Gents, very glad to see these ideas - have been wrestling with this very problem for years. Have had a DeWalt RAS for 40 years, and the dust is still in my ceiling lumber stacks.

At the outset I bought a wire-and-plastic-sheeting contraption sold by deWalt - it did not work or last. Then I made a plywood and laminate large hood - kept some of the dust at the back of the table, but although large - did not prevent the dust plume from contaminating the air. Cut an aperture at the back of the hood, in line with the blade, made a box at the back with a sloped back wall, dropping down to a removable bin - the bin fills up quite quickly, but the plume remains defiant. Added suction to the outlet on the blade shroud - helps a lot in ripping, not much in crosscuts.

As this is my primary tool, I use it for all cuts except breaking down boards. So I was thinking of a catcher that swivels with the saw, but this will be finicky, especially as it will have to clear the fence in crosscuts, and have to be in front of the carriage in in-rip and out-rip positions - way beyond my level of inventiveness. I am a shrink, not an engineer.

Since most of my cuts are crosscuts, I think I will steal Art and Herb's ideas. After seeing Doug's table in another post, I realised how inadequate my setup is - due for an upgrade.
