Hi,
I have freshly scraped headstock bearings on my machine. I tried to highlight high spots with blue colour. Please see pictures:
I hope it is good quality scraping. Do you think I can run my machine's spindle?
To be honest, it wasn't me who did the scraping. It was a company that professionaly refurbishes machines in my country. I didn't want to mention that, intentionally, not to bias anyone. But obviously I biased everybody that it was me who did the scraping - I'm sorry for that.
The brand of the lathe is Czechoslovakia's TOS SV 18 RA - the company refurbishes them very often.
So if you say the bearing needs 50% contact and I have maybe 2% then I think I have some argument they did their job not perfectly. They also ground the spindle itself (bearing surfaces, spindle's taper). I measured spindle's runout on its taper with spindle in these bearings, and I think it is pretty good (no runout visible with 0.01mm indicator).

Honesty is the best policy! Did the rebuilder give you a guarantee? If he did talk to them first. What country are you in?
