Have been working with a local Wellington Jeweller who has a wax RP printer with 0.0254mm resolution
The first thing I decided to try making was a wheel for the Druff's K/J/Ab project. I had tried this through shapeways in Ultra fine frosted detail but was somewhat disappointed with the result. So it was time to try something else, the wax printer makes a master that can be cast directly, only problem is each wax costs $30, but once cast the brass is good enough to use as the master
We tried the same design I had sent to Shapeways but the spruing and how to turn the final wheel were still unproven and looking difficult. My Jeweller suggested we sprue the wheel from the front hub and this is the final design.
The plan now is to send this back to Morris and Watson as a master for casting in bulk (well maybe 10 at a time as I'll need two tyres of practice to get eight good ones)
