J. Phil Thien's Projects

Does it make any difference if the dust/air is blown into the Thien baffle vs being pulled through it like a normal set-up?

I recently picked up a DeWalt DW735X planer & it has a built-in chip exhaust system that blows the chips out of a port on the rear of the machine. The planer comes with an adapter to connect it to a 4" hose, using a hand-held anemometer I'm getting about 225CFM of air flow out of the 4' port.

I've seen several YouTube videos of people with the same type of planer using a trash can style Thien baffle to collect the chips with just a small filter bag on the outlet.

Would a top hat style Thien baffle work with just the 225CFM from the planner?

Hello I'm new to the forum & looking for basic information & any tips or suggestions on building my first Thien style separator. I've read a lot of threads here & on other forums & I've watched a bunch of videos on building the Thien style separators.

Here's the items I've gathered together so far for the build!
1st is a Cincinnati 200S barrel style dust collector, Here's a pdf link with the specs.

For the filters I picked up 3 surplus canister filters! I originally only planed to use one filter with the set-up & keep the other two for back-ups, But I may decide to go with dual filters if using one filter creates too much of an exhaust restriction? Here's the specs. on the filters.

For my collection can I'm using a heavy duty 32 gallon galvanized metal trash can.

As for the construction of the unit, I'm pretty much going to try & follow the information on this old thread by "pitbull"http://www.jpthien.com/smf/index.php?topic=429.msg2187#msg2187 I noticed that "pitbull" hasn't posted since Oct. of 2014! But his method of using the kerf-cut plywood is basically how I'm making mine.

In my case I got some pre-cut kerf material from a friend that was left overs from a cement forming project. The material is about 9-3/8" wide & about 7 foot long so I should have more than enough for the project! Probably enough for a another smaller unit made for my shop-vac, Provided I don't mess-up on the first attempt.  ;D
