« Part 1: Doctor Octopus Part 2 of Dust Collection overhaul series Part 3: "If you build it," it will suck »

After disassembling Doc Oc and thus breaking some of the blast gates because I taped them together SO well, I moved the Craftsman 113 back to the corner:

I reconnected it to the old 2 1/2” vacuum tubes for the older tools and and started the 4” run. I started looking locally (as I always try to do) for parts and found plastic connectors but I didn’t want to use PVC for the runs because, again, I read on this site that metal is better. So I began trying to mate the plastic and metal together. Not a great fit. The run out of the intake of the collector is plastic so I just made that whole tree plastic. To make the run in the ceiling I switched to aluminum. I used some regular and some galvanized, the later being more expensive. After putting in the first pipe with the connection end facing the incoming dust, I realized it would collect on the crevice. I then used a plastic connector to make all the aluminum pipes go open end towards the air flow.

How small is it going at the yellow blast gates? I’m no dust expert but i’m guessing you are losing a ton of suction at those

That is the old 2” run and yes, I lose a ton of suction there. But that only feeds my old belt sander and radial arm saw. Right now I only have 2” collection hoods for those. The new 4” run can be extended to those later. I have orders and projects backed up for weeks so I had to stop with the table saw, jointer, planer, router table and drum sander.

I agree that metal ducting will serve you better over the long haul.

My main concern is the size of your dust collector. That looks like a collector I would hook up to one tool at a time. I’d be worried there isn’t enough CFM to collect from a tool across the shop.

I started with a portable 1hp dust collector with bags. It looked a lot like your collector, but a different brand. It had a small impeller size (maybe 11-12”) and was underpowered even for one tool.

I then switched to a wall-mounted full size 2hp cyclone with a 14-15” impeller and it is night and day more powerful. It can handle 6” metal duct to all my major power tools.
I just don’t think that Craftsman was ever designed to be a central dust collector unit.

Hope it works out okay for you.

You are right, pintodelux (a deluxe Pinto? Is there such a thing? Orange? my dad and brother had Pintos) that old Craftsman dust collector isn’t powerful enough but that’s what I inherited from my dad. I’ll eventually get a bigger one but I’ve spent over $8000 of gov. economy stimulating money to upgrade most of my shop. I figure I should make some more money with these tools before another buy!

Thanks for the advice.
