The final outcome.
Monday 7 June 2010
After the failed attempt at wax casting the pins i decided to turn to j-cast which is kinda like plastic. I casted the brass master pin in RTV (LATEX) in order to create a mould for the j-cast. The j-cast went ok ish its a good material to work with because you can colour it. The j-cast is quite fragile so i have decided to lathe the pins from aluminium.
I aim to use the brass master pin in the final design however i also want to create aluminium pins too. I use the brass pin to create a rubber mould that would allow me to cast wax multiples for firing in the kiln. The wax is melted out and replaced with molten aluminium. Big problem however the wax models are really fragile and keep breaking.
I need to find a better method.
