I’m building up my garage woodshop, and I have most of it laid out in a way that I think will work. I’m struggling with the dust collection parts, though. Since I’m acquiring a lot of new (to me) tools at once, I’m trying to find good deals. Today I picked up one of these Shop Fox 1.5 HP units locally (as part of a package deal with a 8” Jet benchtop jointer/planer):
My first issue is that this unit has a 6” inlet, reduced to two 4” ports. My TS has a 2.5” port and my router table, the jointer/planer, and SCMS are smaller than that. I don’t yet have a band saw but I believe it will also be 2.5”, if I get either of the two Delta ones I’m currently looking at. My intention is to build a new cabinet this weekend for one wall of my shop that will also become the stand for the SCMS and the router table. Given the amount of dust that the SCMS generates which escapes dust collection entirely, I intend to put in some sort of scoop behind it to try and grab what it throws back at the wall. I want to tie that scoop and any other collection points (on tools or otherwise) into a single line that runs hidden within the cabinet. I’ll put reducers and blast gates in all the right spots for all the various tools, but I’m thinking this branch of the line should be 4”. Then I’ll run another line from it overhead and back down to the other wall where the shop fox will live. Does this seem sane?
My second issue is filtering – my previous DC solution was just a little shop vac. While it is loud, small, and fills up quickly, it also has a HEPA filter to get a lot of the really fine dust. This new dust collector does not have that filter. It only has the bags, which according to the link above are rated to filter out stuff down to 30 microns. As I understand it, this still leaves lots of fines for me to breathe in. Is there a way to replace those cloth bags with a top filter and a bottom plastic bag? Or some other solution that will get the smaller stuff?
Lastly, I simply do not have room for a big clearvue cyclone or anything like it. I might be able to squeeze in a DIY chip separator or something to get the big stuff before it goes through the impeller. Is that a good idea? With all the chips that the jointer/planer will throw off it sure seems like something should stop them before they get a chance to whack some impeller fins.
I’m a total woodworking newbie, but I do have a background in engineering. I tend to overthink stuff, so I’m hoping that you more seasoned folks can help steer me in the right direction.
