epoxied blocks together and milled it out with boring bar.

Could you share a photo of the bit? I'm curious as to the amount of deflection on such a long tool. Small, steady cuts?
That and cleanup - LOL..

I'll get a pic of it tomorrow, it's an 8" bar with carbide tip, 5/8 in dia. I took 3/16"to 1/4" at a time till the last pass which was only about .020- .035 of an inch. No clean up needed on the wood it's smooth as a baby's butt. This was done on a Bridgeport Milling machine, tool deflection is zero when cutting this wood even with the 8" bar. Each revolution of the bar would mean .006 of an inch downward travel causing a smooth finish. This wood is one of the hardest at a scale of 1400 compared to say pine of about 400 on the wood hardness chart. If I was using Pine, there would have issues trying to hold it tight without damage by either wood deflection or vise crushing it trying to hold it. The vacuum did its clean up all around the Mill if that's the cleanup you mean, there was plenty of that!

Wanted to seal the shifter slot so no debris fall in when shifter is in place. I used the Milling machine again with a T-slot cutter to make the slot for the plastic seal to slide when the shifter is moved. click image for video

also got the cup holders holes cut. and put 1/4 corner round edge on the shifter slot.

Navy, it's a boring head & bar for boring engine blocks, right? And the hardness numbers you noted are the Janka Hardness Scale, which is like Rockwell Hardness but for woods vs metal, right? Thinking your wood is one of the maples, like Curly, Hard or Birdseye? Beautiful wood, and nice work!!Roger
Enjoy the little things in life, and you may look back one day and realize that they were really the BIG things.

In the video I think I see a "Boring Head", but your explanation says "Boring Bar".
That's why I was asking about deflection. A picture will be great when you've time. !/4" cuts in some woods can get nasty (as you already know) - again, the reason I was asking to see the cutter. You know I am always curious right? LOL OH, and YES I did mean cleanup of the mill. I hate sawdust in the metal working tools! It seems like the felts on the way wipers will be puking small piles of oily sawdust for weeks / months after.
