@Norton I looked at disassembling everything, but I was concerned about breaking something. The motor itself had a bit of a standoff due to the mounting screws, so I did not think the heat would get to the motor or wires. I went ahead and used the solder tip which came with the micro-torch. Cleaned up the brass, fluxed, applied heat to a pretty small area and got the solder pad formed. Then re-attached the wire using the torch tip. I was rather surprised the soldering iron (pencil) would not provide enough heat to re-attach the wire even with the solder pad down.
It must take a lot of skill and patience to solder these brass engine kits together. Hats off to you guys. Jeff
