In the old days highly skilled woodworkers would painstakingly carve patterns for castings. Years ago I was in such a wood shop and marveled at the detailed and intricate work I saw. These patterns would then be sand cast to produce the pieces they needed. A steam train would have hundreds and hundreds of castings which would then be assembled.
As we create our train we are seeking to replicate this work, but instead of doing everything by hand we are using modern software and the ‘castings’ are routed on the MultiCam from sheets of Precision Board. The stack of cut pieces is growing fast!
