I meant to post this a few weeks ago, but other concerns took priority.
This is part if the lot of C-Liner parts Randy sent to me in exchange for the Rivarossi 0-8-0 boiler front.
The lot contained two clear early 60's frames. One was mostly complete, but Randy thought the motor was burned out. It was kind of a mess, and the commutator form had partially melted. These first generation motors had commutator forms made of a very low temp plastic, so it didn't take much deferred maintenance to melt them. I still don't know how they managed to solder the windings to the plates at the factory without destroying it. I think this one fell victim to a missing insulator on the brush V spring, which probably glowed a nice bright orange when the throttle was applied.
I used a razor blade to cut away the melted areas, then sealed the whole thing with several applications of Zap CA. I turned the armature in a drill and trued the plates, starting with 220 grit sandpaper, then working my way up to 600 grit to polish it.
This is where the melted plastic covered the plates. You can see a gap in the top of the form, but it's rock solid now. It runs beautifully, and paces the same generation clear unit in the background perfectly. They work great in tandem.
The IC shell is also of early 60's vintage, and was given to me by a friend as a thankyou for advice with getting his collection up and running. I had a spare lead fuel tank weight in a parts box to replace the missing stack of steel weights that were in these first gen units, making it the only non-period part on it. No biggie, and it can be removed with glue solvent if I ever find enough plates.
So thanks Randy. They found a good home.
