Not planning on welding, but for big trains, we have discussed wheel materials a lot and basically came to the conclusion that 4140 or Ductile alloy would be the best for wheels, NO cast iron or anything but steel. Mild steel works but wears much quicker so for the $1 or so extra each the 4140 seems to be the best. I know nothing about metal besides what I have been told but am very concerned with safety and plan on making my stuff 'adjustable gauge' with spacers and clamps
so I can visit other railroads in the west. Most are 15" or 16" gauge, though I like the bigger and more stable 18" gauge for real hauling rather than just a 'scale model'.
I currently need 8 pieces for the car and speeder. Four are 8.5" diameter 10 lb weights, four are 9.5" diameter 20 lb weights, I plan on turning them all down to 8" and sweating on the tires. I hope to NOT have to add hubs but may end up doing that too (the 10 lb weights are only 7/8" thick so may not mount on the axles well...)
Here is a nice photo of a 5/8 scale motor car on the Redwood Valley Railway 15" gauge line in 2004. Unfortunately, I never got his name, but REALLY like his ride!
