About the only thing I might have done differently in design would be that I would make the thread a 40 pitch and leave a straight, clean ring of the major diameter of the adjusting nut to allow inscribing .001" graduations. That would make it a micrometer carriage stop.
What pitch thread does it have now? Looks like it might be about a 20TPI. If that's the case the adjusting nut seems big enough that you could turn a short (1/8"?) wide diameter just below the depth of the grooves, make a press-fit aluminum ring and inscribe 50 graduations around it.
Just a thought.
Ken,
When I originally designed the carriage stop, I had designed in a nut with tick marks to act as a micrometer type stop. That's why I used a 20TPI thread. When it came time to finish the project I got lazy and just made the knurled nut figuring I could always make a micrometer nut for it later on. I also want to make a dial indicator attachment so I can hold a DI and use that instead of the stop. I'll probably make the DI attachment first, then the micrometer nut.
Thanks for the comments.
