I've been putting some time and money into the CNC controls and I'll be adding that as a separate sub-project. Most of the components for the controller, drivers and motors are purchased and assembly is underway. I'll document it in a separate sub-project.

I picked up a Mitutoyo 155-903 Telescoping Gauge Set on eBay for $60 (list is ~$170). My cheap Chinese ones just don't work right - poor manufacturing. This set is used and was listed as having a broken unit (plunger missing on the smallest one) but the missing part was in the bottom of the wallet and just needed reassembled. It also came with an extra B size gauge. A bit of light oil and a couple of Kim Wipes and they work like new.
