Hello all!  Hobbyist woodworker from Central Florida here.  Been getting serious about it for last decade, but been playing around in woodworking & carpentry for 40+ years. 

In my small shop, I have been using a Dust Right separator with my Shop-Vac for a little while now.  However my Shop-Vac just died about 2 weeks ago. 

Grizzly had their 1.5HP wall mount DC with HEPA canister filter on sale for July 4th for about $720 shipped to my door, so I bit the bullet & made the purchase. 

Now I have started my own Thien build since the Dust Right only has 2 1/2" hose connections.

Hi folks, I am Bob Crane and I live in southern Ontario. I have a couple of design/engineering questions about Thein seperator design. All of the limited engineering skills that I have lead me to believe that there is some defineable relationsip between the diameter of the baffle chamber and the cfm rating of the air supply. Vacuums are slower yet more powerful that blowers. Does the air speed  affect the seperation efficiency and is there an engineering formula to follow if I know the cfm of my vacuum? My second question relates the thickness of the secondary baffle. I am building a "top hat" seperator and find myself wondering if I should use 19mm ply or 1/4" mdf. All feed back is welcome and thank you for allowing me to join.
