Always the problem

I will get to work on a sketch, the trick is that there is always one more graduation on the same length of actual dial as compared to the vernier scale. The other "trick" on this project is the mental jump beyond the base 6 of the dial increments, as the actual size of the increments is less important than the relative scale of the increments, the magic number here is 110%.

Each of the increments on the vernier scale need to be 110% of the length of the increments on the hand wheel. And you need ten of them. so standby for the image.

I'm 99% positive on this, it feels right, but the usual disclaimer applies, Check it yourself first and be satisfied before cutting metal, incidentally it's the positive and negative directions that are likely to be an issue as these are always a bit confusing, so I'd do a trial assembly and test before marking these.
