So I wanted to improve the dust collection of this beast, and I still have a few other projects to get to before I can take time to build a miter saw station proper. After quite a few different iterations it became clear that implementing something that would handle ALL of the cuts and sizes this saw can handle was impractical, if not impossible. So I settled for something a bit less sophisticated. The setup as shown will handle anything up to ~1” thick, and the vast majority of stuff in my immediate future is 3/4”. The sides are removable, so if I need to cut something thicker in the future I’ll make short versions that will have the right clearance. Now that I’ve got the basic design down it won’t take long.
The dowels on the top I was going to use to secure some vinyl sheets to help seal that area better, but it really isn’t necessary, and I’ll cut them off at some point.
The 2-1/2” fitting on the side fits my rigid vac hose (which is connected to a dust deputy), and was a multi-adapter from HD that I just cut off and used a rasp to open up the ID as much as I dared.
It is made from two halves, the left has two 3/8” dowels that line up with where the stock dust collector snout mounts, and the right side has holes to pick up the dowels. Two drywall screws pull the parts together, and clamp it to the frame of the saw arm.
Keys to making it work well:
45 degree on the back. Initially I just had it flat, and it was basically a ‘dead zone’ for air flow. For thicker work I’ll have to make another one.
3/4” piece behind the fence:
If it isn’t there, when the rear of this thing clears your workpiece it creates a gap and lets a lot of dust out the back end.
Seal off all the gaps you can – as you can see with my awesome tape job.
If I’m just trimming a small amount of a piece I get another piece to put on the outfeed side so there isn’t a big gap as can be seen in the second photo.
It’s crude, but effective. The dust you see is from four 12” wide cuts on some 3/4” mdf. Some tape on the bottom of that 45 piece would probably eliminate most of that.
It takes about 30 seconds to remove and put the stock collector back on.
Edited to add my high-tech bandsaw dust collection, don’t laugh, it actually works well.
