So, finally, I have my Mitutoyo DRO installed. I bet I've got 15-20 hours into this thing and this is revision 4.8.
First, I abandoned putting in a stop. There's a horizontal section of casting that precludes one from using the factory hole unless I cut the casting which I decided against.. I'd need a much larger piece coming off the spindle collar to thread in the stop to put it in front of the faceplate and I felt that would obstruct my view more.
That horizontal casting also stopped me from putting the DRO bar behind the faceplate. The hole I had made in the new faceplate fit the DRO perfect and was in the right location but the casting. Of course, I didn't 'discover' the casting in the way until I was on revision 2.
I ordered a new faceplate without the rectangle cutout. I tweaked the faceplate by reducing height by a few .01" to get it to fit just perfect and had the corners rounded a touch more.
I liked David's use of the rotary table for the spindle collar so I had to copy that, twice, maybe three times. It looks like it was done by a 10th grader in shop class.
I'd say there's no way I could get paid to do machinist work. My hourly wage would be .57 cents.
