Bill has a detailed plan here, if this is something you hadn’t seen:

He has developed a spreadsheet where you enter some things like inlet size and blower power and it gives you the dimensions you need.

I didn’t study it in detail, but the spreadsheet is interactive and even changes the dimensions on the drawing (which is a cool Excel spreadsheet trick I’ve never seen before).

I put in 2 HP and 6” inlet and it seems to be a design VERY much taller than yours. The upper cylinder is about 28”, the cone is about 40” (68” tall total not counting blower or waste can), and the inside cylinder is about 22” long.

Oddly, it looks like the cyclone gets shorter with a high power blower. Maybe that’s because the air speed is higher and it doesn’t need to be as tall.

Again, I just played with it briefly and there are likely details I overlooked.

I think the spreadsheet allows you to force some dimensions, and it will then optimize the others, though this wouldn’t be an optimum design overall. Just the optimum for the dimensions you forced it to use.

I applaud your efforts in building your own.
