From watching Joe Pie's video, it seems I have not gone too far. I have not gotten to the point of breaking off the diamonds. I haven't quite formed diamonds yet. That's fine for what I need to do.
The next piece I did was in 12L14. It was just a tommy bar for my ER32 chuck that I had made and wanted to knurl. This bar would get a little greasy when using, so I thought a knurl would help. I knurled 6 inches of the bar. The knurling depth is not even. It is better formed near the tailstock and less so closer to the chuck. I do know my tailstock is not centered vertically with the spindle axis - that is another mini-lathe project. Guess I need to adjust the pressure a little along the way. Nonetheless, the knurl is functional. Machined a couple of grooves to give it a little interest. For some reason my phone isn't uploading the photo. When it's uploaded I'll post it.
