Needed a mandrel to mount the gear cutter. (I have a Chinese one that I use on my slitting saws, the run out is so bad only one tooth cuts, the blades should last forever using one tooth at a time)
Wanting minimal runout and too lazy to mount the 4 jaw and dial it in I tried trimming the last few thou on the mill. Shows zero runout now, will be interesting to see how it is after we remount it in the collet.

Bored the bottom washer to make the mandrel more universal.

Free advice is worth exactly what you payed for it.
