Quoted from cobra18t:
Do you guys ever CNC probe scan a ramp and then CNC a new mold from the scan? It seems like that could be a nice way to do it with lower risk to the donor ramp. You would then have the ramp scan or mold 3D model that you could propagate to other people if you wanted.

I am sure its possible, but CNC cutting a ramp mold would be very costly. You would need to sell hundreds of them to get your money back.
