A fine brass pilot for the Ft Wayne Interurban Combine
The Fort Wayne -Lima Interurban combines and their sister cars had some very light steel pilots. 3D printing such a fine piece in resin is impossible. For this part, I will try out 3D brass printing. In fact, not the brass is printed, but the lost wax moulding. This process is expensive, but permits wall thickness down to 0.5 millimeters.
One pilot would cost as much as the half of an entire resin printed carbody. But it is worth to be tried out.
