Wow that was great! I didn't expect that nice of a result with that small cutoff tool. Well done :)

@adisharr

Yes, thank you for your comment.

With my micro-tools design the results are very cool.

@princeigorash

Thank you too, and thanks for your question,

Well, in this case I use a small Sherline lathe because is the only one I have here in this video in the case, but a big lathe make it more easy and without risk.

Very cool you being a student of the "Politehnica" University of Bucharest.

Best wishes from Brazil to you in Romenia

Such operation can be done on a bigger lathes and bigger semifabricates (your case the pulley)? Or it is considered too risky?

Thank You.
