So I finished this build...mostly! I'm thinking of it as a "proof of concept"...
I decided not to do anything to the dial other than drill the markers at the hour marks, larger markers at the 12, 3, 6 and 9. This actually proved a problem after I remounted the dial and noticed that because the centerwheel pinion is off set from center, the minute and hour hands don't quite line up with the markers...not a huge deal though! Having said that, I think the dial looks Wonderful as it is! The simple dial/ markers really complements the "Busy-ness" of the skeleton movement.
I also had to turn a back "Dial" to make up the difference of between the size of the movement and the size of the exhibition back crystal. This picture looks "deformed" but actually was taken at an angle to capture the best light.
All in all, It will be something I do again now that I have an idea of what problems can and will arise when combining parts that were not designed to go together!
