Re: [CAD_CAM_EDM_DRO] Machineable wax - watch case lugs

Hi Bill,

With most 'traditional' watch case designs there is a clean, right-angle
join between the case and the strap lugs. I don't see how I could achieve
that purely by milling as I would inevitably get a radius. Also, on many
case designs, the strap lugs have some form of pattern on their outside
face. This could probably be done quite easily if the lug was separate but
would be quite difficult with it attached to the case. I think one of the
other suggestions may work which was cutting the case as metal patterns,
soldering them together and then amking a rubber mold and casting waxes from
that, However, even here I would be a bit worried about retaining truth in
the shape of the case. Perhaps I just need to mill the bits in metal and
sort myself out some form of resistance welder to join the bits together,
