Topic tags/keywords: trick tip

I have been seeing a lot of dust collector (really heavy sediment collectors) on LJ for the past few months and it got me to thinking. I use a 16 gallon shop vac with a hepa filter and a collection bag. With the bag, the filter stays pretty clean, but, bags are expensive. I also have a Master Mechanic shop vac that is over 30 years old and it has crapped out on me. One of the great things about the MM shop vac is that it has the intake and exhaust on the top of vac, right next to each other. I decided to use the MM shop vac as my sediment trap in the vacuum system.
I removed the motor from the MM shop vac and cut a disc of wood to fit in the motor’s position and glued it in with expanding Gorilla glue. The intake port has a kind of hood that protrudes into the canister creating a bit of a directional spin. The output, the old exhaust port, is hooked up to my 16 gallon shop vac and it seems to work like a charm.
I plan to continue to run the 16 gallon shop vac with a bag for the filter protection but it looks like it will be a long time before it gets filled up.

Good plan Gary
I have used a shop vac in my router table for years and it has worked great.
