    PM is complaining that I cannot upload more than 5 pix per post, and there are only for pix in the above post. Go figure. Anyhow, here is the Acu-Rite pinout for the Master MP readout.

    Make sure whomever hones the bore knows how to deal with the key slot and quill lock cutout. I don't think they necessarily need a helical hone, but they do need to be careful not to snag or round...
