Hi Guys,
The engraving thread and vernier protractors sent me down a path I've been thinking about. Namely making a protractor at better than 1
0 accuracy.
I have at home my cheap and cheerful Chinese combination set so I started to play with it and see if it was feasible to add a vernier to it.
Took a few measurements stuck them in my CAD program and got a scale sized vernier to sort of match the set.
Some careful scissor work and some woodworkers glue and we have a vernier at 15' divisions.
Now that I know a vernier scale can be added I will set up the RT and engrave one into my good Starret.
Hope you find it useful.
Best Regards
Bob
