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.

Hi, I am also a Philip, and I have been doing wood work since 1957, my Seventh BIRTHDAY, I was given a "WARDS" Lakeside brand 16 ounce hammer, a carpenter's saw, etc.

I have built Stick Homes, Log Houses, Hardwood Floors, and finish carpentry.

Today, retired, I keep my hands busy with smaller projects, as well as working in other media.

My WOOD SUPPLY, includes species that folks do not see often, I have several Square Feet of MADRONE milled in the N.W. corner of CALIFORNIA, as flooring, and when I found it I asked about why it was hidden away: My BOSS told me it was from a Special Flooring contract, and he ALWAYS skept 10% of the contracted footage in case they needed repair, It WAS in the CONTRACT, for customer protection.

He had completely forgotten about it, and as he thought, WELL, it was almost 20 years old, we were talking in 1992 . . .

So I will be doing a Winter Project from it. IN 2025!!!

I also have quite a bit of Rock Hard MAPLE, the species used to make bowling alleys, WHICH was where I got it, a remodel, REPAIR of the first 10-12 feet of each lane!

I asked what the crew would be doing with their "waste" and was soon loading it into my Subaru Forester, Two trips to bring it home!

Does anyone else get SALVAGED WOOD that way

Hey folks, my name is Ray.  My wife and I are both handy, we have always done more remodeling type things than woodworking, but as our remodel wound down, we remodeled our garage into a woodshop to have an outlet for our handy energy and are now relearning woodworking skills to add to our remodeling ones.  I decided to take air quality serious, fist build for finished shop was just a filter dust extractor, it gets a lot of airborne dust.  But now am building a hot rod HF dust collector and of course incorporating a Thein. 

I'm really pouring my all into the build and have read a lot on here... I am going at it with the goal of maximum efficiency knowing that loss of power in a DC system sound like death by a thousand cuts often, not just one big thing.  My first passion in life is aviation, general aviation flying small planes.  The reason I mention this is two fold.  On my old 1947 Cessna 140 I set out to lighten it so I could haul more, I told folks my goal was 60lbs, they laughed at me.  I set out with the mentality "ounces makes pounds" and left no stone unturned to eliminate unneeded weight and I pulled it off! That is how I'm attempting to get my max cfm out of a 2hp system.  My second related thought is I currently fly a Mooney, Al Mooney designed the basic design in the 50s with pencil and paper, by in large same design they used when they last produced some in the 20-teens IRRC.  My airplane can fly at 150kts, and hauls 1050lbs, all other general aviation airplanes in that class are getting pulled around by 260-300hp typically, mine does it on 200hp.  All because Al was a "mad scientist" for efficiency.  So I'm trying to learn from all and bring that mentality into it.  I will share the build in detail once all done. 

Thank You to all who have posted here, letting us newbies learn! It is very appreciated
