I did the 5 gallon bucket modification that replaces the plastic bag and my results were not good. The modification created a lot of air flow turbulence and increased back pressure reducing the suction. How I know this is I have a gauge that reads inches of H2O so I know when my air filter gets clogged to the point where it needs to be cleaned. The gauge went from reading 1 -2 inches of water column with the bag installed to over 5 inches with the bucket mod installed. Here’s the mod video at Stumpy Nub’s “Single Stage Dust Collector Modifications’

Honestly, when I saw his video I thought it was a relatively silly idea. Like a lot of the things he does, it’s over-complicated. You might as well just have a bag down there, even if you can’t do a trash can separator. Changing/emptying the bag isn’t a huge deal, in my opinion.

I figured I’d try it for the hell of it. All it accomplished was to waste $30 in materials and a few hours of my time. I think the problem is the plywood ring that the bucket attaches to is too close up to the separation cone that’s inside the housing and causes back pressure. I have a super dust deputy and I barely get anything in the bag anyway. Oh well, I hope I save someone else the grief of doing this mod to only see the same results I got.

I found what the problem was with the increased backpressure. It was the small deflector used to direct the dust into the bucket opening. I went back and tried different sizes and shapes and locations for the deflector and found one that gets the backpressure down to and actually a little less than with the bag. It’s amazing how one little piece of wood and screw up the air flow.
