Roman portable sundial WIP

[MDF]

Hi Guys,
I recently post a tutorial on a bronze buckle and some people have appreciated, in another post recently spoke also to seek new tutorials so I post a new work in progress of one of my latest works... I hope someone appreciates.

This is a very very special project, a portable roman sundial in bone and bronze stored in Este Museum.
It 'a fascinating and unique item, too bad that the museum does not allow you to take pictures :evil: :evil:

Here you can see an interesting article on this sundial link

This will be a fully functioning replica because the hour lines are calculated for my specific latitude!

Finding a bone suitable for this work was very complicated because some measures were needed hard to find, after some research I opted for a ostrich bone .
Now I do not find the cap bone of similar thickness so opt for a substitute ... cattle or deer horn or wood ... advice on the most appropriate material are welcome :wink:

As usual I post multiple pictures that describe the process, I hope not too many ...
