This is great Rick, thanks again! 1 to 2% stepover on the v bit was kind of what I was expecting. I’ve also gone back and forth on doing the V bit before the clearance bit. I haven’t been able to prove one way is better than the other. The clearance first is definitely easier on the v-bit; especially for deep inlays.
My first attempt, messed up the alignment between cuts a bit. Next time I will use dowels in the bottom to get it perfect.

Your inlays came out amazing. I have yet to try an inlay but I will trying one in the coming weeks.
I’m curious how you determined your parameters. For your tbn but I see you went with a relatively slow 12,000 rpm and your plunge rate is actually faster than your feed rate. I’ve never seen any do that before.
But what I’m even more interested in is the how you came about your start depth and flat depth for your male plug. I’ve watched plenty of videos on deep inlays with a tapered ball nose and from what I remember, their start depth is always greater than their flat depth. Can you tell me a bit about your process and how you landed on those numbers?
