I have a MDC RTR shay. It is two trucks and I bought it at a very good price last year.
The middle axle gear was broken for some time as I looked for alternatives and found a NWSL set that had very tight axle gears that should simply slip on.
The problem was the axle as it came out of the shay offered no obvious way of “disassembly” Out came the big wrench. (something like 50 scale feet) 10 seconds into trying to find a way to get at the axle I managed to destroy the entire wheel and axle combination.
I am ready to decide if I need to contact Roundhouse for a axle/wheel peice for this loco or cut my losses and offer the unit on ebay as it is now.
What do you think? Do I sink more funds into the unit or sell it?
