Hello!

I've had this running for a while and I'm very pleased with it so far. Using a ordinary vacuum cleaner  found in a dumpster as a blower. I may build a "real" blower in the future but I'm in no hurry...

I've used a trash can bin in stainless steel for the walls. I made a prototype with clear plastic but it cracked more and more. It is a rather small radius...Now its clear plastic in the top and the baffle instead. Good to see if any shavings get stuck on the baffle. Happened a few times when doing hand planing.

Extremely fine dust makes it to the walls of the bag in the vacuum cleaner but it is very small amounts, I've emtied the dust bin at least 10 times and it is still just on the wall. The bag and the HEPA filter in the cleaner hopefully makes the dust stay there and not entering the room again.

Thanks Phil and everybody contributing to this forum!

Hello!

I've seen some constructions with double height chambers and even more than that. Wondering: what about to have the slot going all the way around and fix the baffle with rods (unless you're a magician...) for these increased height chambers? When the inlet is far away from the baffle the air stream isn't going to hit the baffle before going around one to two times...

Is the 120 degree solid part important anyway?
