Bill- A Sanford SG-46 surface grinder. It was Ray Hasbrouck's. At one point it was the earliest known serial number according to a fellow who was researching them. An earlier one did surface later.
I was very forunate to have had the opportunity to buy it at a very, very reasonable price. Ray's son was very good to me and really helped me advance my tooling wares.
Pete- The cotter pin is a little bigger.
Doc- No microscope. I've said this before, but it worth repeating, it's like a pilot flying off of instrumentation. To go really small you just go off of the dials. You also need the correct size tooling, but it really does come down to the dials.
Thanks Chris.
