whoa, interesting, voluminous thread. Not sure, maybe someone covered this already:
- you are eventually going to cast the piece in bronze
- dont want the wax to slump while modelling or being handled in the foundry
- do want some ability to reshape, tweak the work as you go
- and have some up-front idea of the shape of the work (e.g a human figure, long tall thing, etc)
Then try making a copper wire "skeleton" armature that is completely internal to the modelled wax. It provides some rigidity, can be bent/formed as you go. During the foundry process it mixes with the molten bronze (which is mostly copper anyway).
PS I've never done this personally, but am told it works
