Casting

This is a work in progress. To date I have succeeded only in completing a wood original. 98cm long. 

The shape and lines draw from the 1920s Art Deco style.

 It was originally made on the request of a friend for a garden figurine, but I got a bit carried away.  

The wood original is made from a high density compressed fine wood fibre. I found this good for detail and predictable behaviour when shaping down a fully symmetric and aerodynamic shape. 

Extensive use of wood putty in several stages enables development of sharp curved edges.

 I failed twice so far in casting a good quality concrete copy, via a single stage pour into a silicone rubber mold. 

I think I will need to change to a two piece mold and then cement the two halves together.  Also need to thicken some weak points where the concrete cast tended to break.
