« Part 6: Looking toward the future. Dust collection... Part 7 of Workshop Development series Part 8: The plan moving forward. »

Okay so the discussion / future planning of dust collection really kind of muddied up the waters. I still think I would be better off coming out of the DC, and separator with 5”, and then reducing at the Wye to 4” going to the tool. My biggest concern is providing enough air flow to pull from BOTH the top, AND bottom of my table saw. I MAY just end up going to the separator and out with 5” to the 5×4x4 Y fitting then into the 4” S&D for the main circuits, and reducing to a 2.5” after a blast gate to feed off of the Shark Guard… If that bombs, then I will have to figure it out… Now I just need to get up off my butt, get some 5” hose, a couple of short lengths of 5” metal pipe, and get to work modding the separator for it.

Not sure if I have even mentioned an air cleaner for my shop yet. So far it has been an old Lasko 20” box fan I picked up years ago when my A/C in the house conked out, and I needed to move some air until the A/C guys fixed the system… It had seen a few too many years knocking around here and there, to the garage, back to the attic etc… until the handles and stuff got bashed off of it, and it was about to hit the curb on trash day, when I decided to duct tape a Filtrete Allergen filter to the intake side, and tape up any holes so as to force air through it… So far so good… Except I should have used a coarse filter like a fiberglass mesh on the intake, and THEN the Filtrete on the output so as to insure no unfiltered blowby… I know this isn’t a scientific measurement, but I can tell you that after running the fan / filter gizmo for 2 hours, no visible floating dust remains in a flashlight beam in the shop… I have mentioned this elsewhere, I might as well mention it here. If anyone wants to loan, rent, or sell me cheaply a Dylos or similar air meter, I could really use one. I want to know what is going on with my air…

This setup works, more or less. More than less, but not great. I have been wanting a proper ceiling mount air cleaner for years. After checking out dozens of models, and eliminating most over cost issues (Hey I have GOT to be able to afford it right?) I had a few to choose from. Most did not offer the capacity, filtration level, or timer whatever, that I wanted. I was looking for an AC blower motor, when I found the Grizzly G0572. Now that will fit the bill… So change gets tossed into the coin jar as it were, and I am saving up for it. Now if I manage to get my hands on a right size AC blower, and figure out how to do the timer on a budget thing, I will still build my cleaner. But this is a good option if the other stuff doesn’t fall into place…

So now that I have my shop air handled cleanlines wise… I need to think about making it tolerable temperature wise… What to do? I mean aside from more box fans, or open the garage doors? (Not a good option due to noise and neighbors…) Guess you will have to wait until my next installment…

It all takes time to get it the way you want it.

Yep. And money. Two things that seem to be in short supply these days…

I’d pay handsomely for some more time and money. Just not with time or money…

When you look at the table saw, think of the open area the DC is pulling from. If the underside of the saw is tight, it won’t drop the pressure much on the top side of the saw which tends to be more open, depending on your guard. I plan to really tighten up the bottom of the saw and make sure the sawdust stays out of the corners. Then only the top is an issue. If you have only one tool sucking at a time, and I think that is the rule with hobbyists, a big DC like you have or even I have will probably do everything very well. But the underside of the saw has to be tight. Then using a 2 inch feed to your guard, you won’t have too much problem getting the dust, I bet. I suppose I should now utter a bunch of disclaimers, but you would ding me anyway if it don’t work…................(-:
