Bridgeport R2E3 Milling Machine

An update to my ancient 1941 Bridgeport manual mill retrofit became available. It has the ~1984 BOSS8 control. I never even tried to bring up the BOSS control, but started right in on the retrofit, as I make these control retrofits. I installed my PPMC analog servo interface, and got 3 AMC analog servo amplifiers from eBay. I had to buy all new/used tooling as this R2E3 has the Kwik-Switch 200 spindle taper, my old machine was R-8. I added a spindle encoder to the top of the head.

Here's what my machine looks like now. The interface for the Blum touch probe is on the front of the head.
