I’m trying to get SOMETHING going with DC because my barn is a disgusting dump and I’m tired of it! I have an old Reliant 2HP that I picked up cheap. Managed to rig some 4” plastic drain pipe up to the tablesaw, jointer, planer and router. I stuck the DC upstairs in the loft.

Now for the funny part. You’ll love this. After a couple of hours of working out there, I noticed something was awry. Went upstairs to find that the bag had blown off the DC and the entire loft (lots of junk!) was covered in sawdust!!


I’m thinking of piping the exhaust over to the wall, up the wall, and out the window (probably facing it down with an elbow).

Anyone do something like this? How long and what kind of lift could it handle? Is the exhaust just as powerful as the suction? I understand about air replacement, and will deal with that later. I have an idea about that …

Why not just cut a hole in the wall and exhaust it there?
That’s what I did. Used a 4” chimney pipe to go through the wall. Coulda used DWV or PVC but didn’t have it handy.

Yeah, that’s an option. It wouldn’t kill me to cut a hole in the barn. Just figured I could run it out the window until I figured out where I want it long term.

I was thinking of exhausting it out there into a sealed (in the winter) box with a pleated filter and a “window” back into the barn to avoid the air loss issue.

Just curious how much power comes out the exhaust end to jettison this stuff. By the looks of the loft aftermath, I’m guessing a lot! ;)

Look at the wood whisperer and the way he did his :)

I vent my DC out of my basement. I do use a large chip separator before the impeller so 98% of it gets trapped inside but in a manageable form. The fine airborne dust goes outside. This would also help because you wouldn’t have to push chips through so much pipe. You do want backpressure but you also don’t want it restricted or the motor laboring. Just a thought.
