Try ceramic tooling Dusty. You can't take much of a cut but it will do the job. I cut many a train car wheels with it and those puppies are hard. Surface speed must be high and you must keep the tool in the material with zero interruption..

I'm gettin there with what I have on hand. Still need .020 more depth on the left 3 and a final profile cut on all. Didn't mean to get my totally unautomatic spray bottle in the pic.

Finished the pulley this afternoon. Center drilled it to make grinding the shaft easier if the bearings ever get here.

OBTW the wife informed me that it will be named  Dohasah (pronounced doe-hah-sah), which means 'swift' in Western Apache. Since she controls my sex life, Dohasah is a wonderful choice n I will paint it on the bike.

Got the outside round enough for the band clamp I plan to mount it with. So started the boring part of the job.
Image
The bore is now 22mm to fit the ceramic bearings.

Shaft had a small amount of wear, I'm down .060 n still haven't found the bottom. It finally cleaned up about .020 before I hit 10mm. Far as I can go until the rest of the bearings get here.

How many bearing sizes did you order Dusty ?

Just one size but they only shipped half and I haven't seen the backordered ones. I'll call them and bitch and moan again next week. The large part of the shaft was the only part with bearings, the thin part reaches way into the center of the compressor volute.

Got all the bearings and a few minutes without sumptin to do. Slid 3 into the belt side a spring then one on the compressor side.

Screwed the impeller back on and torqued it.
Image
Thrust was fine without any adjustment. So I put the volute on.
Image
Then I applied a little BBQ Metallic Black cuz it was handy.
ImageThats it till I get the engine in a frame.

I did do the math and the final drive ratio for the first test will be 1 to 15.4 which will give me a little over 46000 blower rpm at 3000 engine rpm. As oversized as this turbo is hopefully that will be enough so that I don't have to have a jackshaft.
