I hope I posted this in the right forum.
I’m getting ready to build me a trash can cyclone for my shop vac.
I have the general idea but have one question I hope someone can answer.
I notice on most of these plans they use 4” pvc plumbing parts.
The question is, is 4” the magic number/diameter or can you use 2-1/2” elbow and straight piece and accomplish the same. Since I have a craftsman 9 gallon vac with a 2-1/2” hose I figured well why not just make the lid with 2-1/2” parts then I wouldn’t have to go buy adapters to adapter the 4” parts.
My thinking is the 4” would make it more efficient, and maybe the 2-1/2” make it too much of a vacumn and crush the can. I will be using an old 13 gallon oil drum which I’ve been using for a garbage can for some time now.
