Has anyone tried to modify the All Nation 4-6-0 mechanism to sprung drivers? I have an unbuilt drive and the frame pieces are 1/8 thick brass. I found some .05 and .06 diameter springs from Precision Scale. They are pretty stiff for their size and I think they will work even with the weight of the diecast boiler.
Before I modify the frame I wanted to see if anyone had tried doing this already.
If anyone has tried this could you share what you did and how it came out?
