Very nice! Automotive type seal.. meaning that you used something in the 62022-23 series? Who did the machining? It's nice work. If you don't mind me asking, for the tube section & rotor.. did you use standard steel pipe & alum / steel or something else that's corrosion resistant? I'm going to take some pictures tonight to show my build, but I'm already working on the next sized unit, which will be a 5.25 billet al rotor with a cast iron section of pipe for the outer housing. Thanks for sharing, and I'd love to see the other pics of the build if you can post them up.
@Mike, thanks for the calculations and insight on the inside aspects of this cool device, and the mention of the other options that I have, which can be easily overlooked if you're only seeing things from one set of eyes...

@AllCanadian, I like the sounds of the graphite seals, I've got a plumbers supply house 15mins away which I use for my steam stuff on my home furnace, I think I'll take a ride tomorrow... thanks a bunch for the info.

-regards,

I just went down to Napa and ask for a seal that fit a 5/8 shaft. Outside was about a 1.33 in. A friend gave me a 6 foot length of stainless pipe. 3/16" thickness.  That is the tube. The rotor is alumium. I built a furnace and burner to smelt the rotor because of the price. (8"X12" round was 586.00) Couldn't afford that.  I did all of the machining myself.
Looking forward to seeing your project also, and thanks for the compliment.

Here's another look at the inside

Hi all

Don't know why I put @ mike on these pics.  Their're for everyone, enjoy
I also spelled Stefans name wrong in the first post. He probably won't speak to me forever

Hey idnick
I think grigg had a wavey outer casing, that is the clearance changed so as the holes in the rotor came around the water in them was compressed then decompressed very rapidly.
