I want to do some bronze casting, using the cuttlefish bone moulding
process - a mould is carved or pressed directly into the cuttlefish.

I have my cuttles. Now I need to machine them a little to make flat
surfaces, interlocking keys etc. Any advice ?

Can I machine cuttlefish bone as I would timber ? Is the dust a hazard
to me, or my machinery ? Will it shatter if I go at it with power
tools?

How should I machine it ? What's the best bit of bone to use? Do I
need mortice and tenon keyways in it, and if so, how do I form them?


Thanks for any advice you can offer.
