After reading lumberjocks for some years now, today I decided to post my last project.

I’m setting up my new tiny workshop and the Bosch vacuum I have, gets filled in quite quickly. I have took the design from Phil Thien’s website. The design was from retired2.

I finally completed the project last night. I’m amazed how well it is working. I wasn’t expecting such a result in the first try. Sometime in the future I’m planning to build a bigger version and mount a fan for my 120mm. inlet thicknesser which is creating a lot of shavings.

Nicely done and love the clear bucket so you know what’s going on and can tell when it need attention.
Plus like the lower height from my home built cyclone, this would be much easier to place around the shop.

It’s been awhile since I built my cyclone and haven’t really paid attention to the facts but are the Thien baffles and the cyclone about the same in efficiency?
I ask this because I really like the more compact shape of this set up.

htl, I don’t have a cyclone to compare but I suggest you read this thread:
It says cyclone adds more drag on airflow hence thien is better at least for less than 5 hp systems.

-- Norman - I never never make a mistake, I just change the design.
