My thought is,.. with steel this sturdy,...(and it is just eyeball ground), but if the inner surface angle isn't true, the splined shaft won't allow the pulley to go off kilter...
If it does,... it ain't as tight as the stock one...
All theory, and guessing,... I just didn't feel comfortable risking it...
If the shaft gets buggered,.. the engine is toast.
But... I could have gotten a bad one...
PSS... I originally went to the scrapyard last week, and the guy said $35... came back on the owners day off, and a different guy said he felt guilty charging me $5 for such a gruddy thing...
Shop around,... and re-shop around...

I'm not saying don't try it,... or do.... just relating my experience...
I was originally photo-documenting to make a how to... with MM...
Hope the pics still help anyone else trying it.. even fail pics might be helpful...
Wish I'd had a lathe... I did it clamped in a workmate table walking in circles...
Dizzzzzzy!!!..

PS... grinder boo-boo's really hurt!... much nastier than a straight cut...
Tiny dig, on my left pinky... but my band buddies are going to call me a "pu$$y" this weekend...
... and I am...
(never run a guitar string into a cut, new realms of S&M...)
...
Best luck... if results are good,... I may take another shot at it...
Enjoy the experience,... of a bike that isn't a cookie cutter custom...
Every mod on this site, is the result of experiment...
