Holy cow, I want whatever vacuum you are using! I use a little 7A 1 gallon shop vac, it’s cool but It could never collapse a bucket.
Those little cyclones are everywhere, they must work well. I think I might try to make one of the other style, wier, I think. Cool project I hope. I got pretty sick last week from the IPE dust, so I upgraded my filters and got a nice respirator. Not a fun experience.
