Sherline Lathe speed scale

[fcs]

Has anyone gone to the trouble of making an approximate, ballpark estimate RPM scale for the Sherline lathe speed adjustment knob? So when I get something that works well for a situation I can note it or share it?

This isn't for the adjusting knob but you could use it to make one.

Interesting approach. I'll see if I can find an old fluorescent bulb and try it. Thanks.

I bought a photo tachometer from Harbor Freight. Used it to label the speeds on the different settings on the speed dial. Did this on my mini mill.
