Dust cyclone separator

[C-Bag]

Wow, while I call my experiment the Razor Pig Cyclone, you my friend TM51 are also a whirling dervish! The RPC has nothin' on your ability to spin off great ideas!

I know this is going to sound weird, but I'd rather learn not to mess with the Razor Pig while its sucking than to rig up a ground. I'm lazy that way, and it's no more of a zap that dragging my feet across my SO's wool carpet My possibly irrational reason for not grounding it too was in the powdercoat process the powdercoat is charged and the part is grounded......if I ground the RPC, wouldn't that make the pc stick to the inside of the cyclone? As it is right now it doesn't. Dunno....

The manometer is also a good idea, but like checking the vac pipe on the top of the pig for powder coat dust, it's somewhat like an old idiot light in a car. It's going to tell me it's already too late isn't it? So far my inclination to dump the bucket out every other garbage day along with my super stingy pocketbook of not wanting to replace the hepa in the vac has worked. More aversion therapy.

While I appreciated matermarks post, it was just like the other stuff I'd seen. There was more sales hype than actual dimensions that are going to help me fabricate the RPC. what I came away with from my search was, there truly is a million ways to skin this cat and understanding the idea of how it works was going to help me more than formulas. I'm a math tard, plain and simple. So I got lucky and I think anybody else if they truly wanted to make a RPC could make one from my pics and brief description. I also have a metal block when it comes to making plans, so what you see is what I got. if I can do it and it works, I'm pretty sure there are way sharper knives than me in the HMT drawer that can do the same.

Wow nice unit. I made one a couple of years ago with almost the same dimensions, and it worked a treat, really well (except for the very fine dust).
That was until I needed to squeeze it into a smaller space, so I reduced the height and it did not perform nearly as well. So, I am experimenting with a Thein baffle model at the moment, results to come.

Cheers

After perusing the input & ideas offered so far, I was somewhat surprised not to see another technique mentioned to indicate a filled state. So here it is, my 'two cents worth'... Next time you find it full, slide a cheap bathroom scale under the contraption; you now have your upper limit. Leave said scale under contraption for use as a level indicator.

Looks like you’ve put a lot of effort into this! For sealing and alignment, I've found that using silicone caulk rather than epoxy can make adjustments easier if things don’t line up perfectly. Also, a shop vac with a decent flow rate makes a big difference in performance.
