A note on the 10k RPM Pully upgrade from Sherline. I didn't adjust the preload in the spindle as mentioned in the instruction as it will introduce more play. While doing the 3rd design (right most) which took the longest to machine, the spindle housing did get a little warm to the touch but not burning. I'll monitor when I start cutting the batch of 10 after the design has been chosen by FJ, the person commissioning me the job.
Ok, that's all for the day. Hope to update you folks soon on my activities in my home shop.
