Well, I stand corrected!

The plunge, advance, plunge, advance shown in the video is exactly what I suggested.

You hit the nail squarely on the head.

Thanks to everyone. I will give the fly cutter, step and plunge a try. I’ll need to do some shopping for the fly cutter and shank and some additional milling before making the attempt. I’ll likely practice on some scrap first. Thanks again!

Ok. What ever you do, please shoot a video.

I tried the step and plunge with the fly cutter and it did not work out well. I did video it, but it’s not something I want to re-live. I kept breaking the cutting insert. So I tried making the grooves while feeding the material. An autofeed would have been helpful. I may mill this down and try again.

Have you checked your spindle bearings for excess runout?
The rake of your cutting tool could also be a problem...

A bit off topic but it seems like the Rusnok company is for sale.

Perhaps someone on this list could buy it and produce this little tool for hobbyists, maybe in kit form.

Just a thought.

That's an nteresting page...
I have some old sales literature for a Chinese Rusnok copy called the King Midas.
