J. Phil Thien's Projects

Phil,
Thanks for the reply.

What about the idea of taking the exhaust port all the way through the baffle to where the exhaust air is actually coming up from below the baffle?
If so, how far down would the port need to extend into the bottom of the can?

Has anyone tried that?  Is picking up fine dust any better that way?

Would having the exhaust pipe extending through the middle of the baffle mess up the rotation?

I am using a big Rigid shop vac and a 18 gallon tall metal can.
Most of my dust is from routing, sanding, table saw, with MDF & particle board, so I get a lot of fine dust.

Thoughts?

How important is the internal Height of the baffle?

Would the Thien cyclone separate fine dust better if there was a taller gap between the bottom of the top of the lid and the top of the bottom of the baffle?
In other words, instead of the internal height being just the 2.5" size of the elbow, would a 5" or 6" internal height and then having the center exhaust port maybe even flush with the bottom of the top?

I'm just trying to make the cyclone do a better job of not sucking up so much fine dust.
Any ideas?
Thanks,
Kelly
