Nice work Washout!

Adaptive clearing certainly looks like the way to go. Jealous as I looked at Fusion 360 the other day then went to download it and realised that was only for 64 bit (which I knew but had forgotten in my excitement). I've only just upgraded to Win7 32bit on a SSD so it will have to wait for the next PC build.

By the way if the only operation on the flipside was the counterbores why didn't you just use the drill press and a counterbore bit? Save cutting the pocket in the wood and setting it all up again.

Anyway, coming together now . . .
