Royce,
Another option would be finding someone with a 3D pantograph. That is how Grandt line
products did and
does their fine detail work in their molds. A good example is the 1/24th scale D&RGW
trucks and wheels
that
are supplied by Ryan Equipment. The tools to produce these as well as the injection
molding were done at
Grandts. The numbers and letters
on the back side of the wheel are done in a spiral and are between the ribs.
Mike's offer to do a cad file from which a pattern could be made would be the modern
method.
Some of the small detail on our tie strips and insulated railjoiners was done with a
EDM electrode that was
carved out to a positive image and then plunged into the aluminum die to produce the
proper bolt head or tie
plate detail. The detail started out as a cad drawing and that data was loaded to a
CNC to cut the electrode.
As you can see there are many ways to skin this cat.
