« Part 10: Overhead dust collection: complete Part 11 of Dust Collection series Part 12: Added 4" branch runs and other stuff »

When it came to to re-engineer my dust collection system, I knew from experience that I will be getting into overhead dust collection. Tis why I installed overhead blast gates and these 6”x4”x6” wye’s. I’ll have 6” to 4” adapter for under the cabinet and 4” to my incoming Shark Guard with 4” dust collection fitting (should arrive Tuesday thanks to Lee!). I looked ahead and researched Bill Pentz and other places about ideas for dust collection. I still have to make 4” blast gates and fit them, but that is no problem after all the 6” gates I’ve made. A note: I am using 28 gauge HD 4” HVAC ducting due to it being much much lighter than 26 gauge. I made sure the 4” is 6” above my head when I walk under :)I also have the 4” overhead duct 8” to the left above the blade. You never know…. and doesn’t hurt at all to be safe.


I am using eye lag bolts through out my ceiling mounting and 12 gauge jack chain.

Some good work on your ducting. I like the eye lag bolts and wondered where you got them.

When I installed mine I debated myself about 8” ducting for the main trunk but went with 6” because I worried that I would have too slow air speed especially when using a 4” dust port on a machine. Do you have any worry about air speed in the 8” duct and having dust settle out.

Looking good. I too have been torn between using 6” or 4” throughout the shop.

Red.. I have a 3HP Grizzly DC. 6” would be my norm, 8” would not work. If I had a 1.5HP, I would really have to dig down the research of putting up 6” or 4” ducting. From everything I read, 4” would be the way to go. But then there are people that say everything is fine using 6”. Be as it may, I have no worries at all using 6”.
As to my eye lag bolts: I came across a box of these things left behind at a job site. 1,000 in a box :) These are mostly used to hang ceiling grid wire for drop ceiling in office spaces, which can be found at Amazon or Grainger or somewhere.
