Machineable wax - watch case lugs

Ian,
Why would you need to attach the lugs to the watch
case body? The art and cutting files could include the
lugs as PART of the body. Turn the piece over, after
cutting the top, then mill out the cavity and area for
the dial and glass.
If you ever need to join parts in wax, use sticky
wax to position one piece to the other. Once the
pieces
are aligned correctly, use a hot wax tool to weld the
pieces together. Just remember to get rid of any small
pinhole voids in the join or you'll get porousity and
blowouts where the pieces are joined.
