Does anyone have photos or patent pics of the Chronart twinface (also called the twindial) clock movement? I have one apart that was water damaged but the alignment of the gears eludes me. I just haven't found the right way up with each one. It has a field coil by Wheeler (#864). Any help appreciated.

OK, I realized what I did wrong and got the train in properly, but I have two more major issues with this clock. First, the field coil appears to be dead as it does not cause any typical vibration with a screwdriver like a Telechron coil. Second, the infamous fiber gear in this one has lost almost every tooth. I figure I might be able to use a telechron coil in its place, but does anyone have a 3d printer or some other CAD type machine that can make a replacement based on the remaining teeth, etc.? PM if you can help.

Hi Chris,

I don't know if you're still interested in repairing your Twinface clock, but if so, maybe I can help. I've reconditioned two of them recently. One had the dreaded fiber gear failure. I found a brass gear from a Telechron clock that matched the fiber gear dimensions perfectly. Using this gear in the Twinface movement required making a brass hub to mate the Telechron gear with the Twinface shaft. I had concerns about noise, but the repaired movement seems to run quietly.

If you like, I can post more information and photos that may help.

- Gordon.
