I decided to use my UV hardening material, Bondic, to build up the broken section of the wheel that moves cards through the punch station. Once I get the material up close to level, I will have to invent a method to establish an accurate radius for the new section. I intend to spinkle grit onto the top layer as a way of establishing a similar grip to the remaining section and other wheel.
It was a very slow and careful process to build up layers and harden them, approaching but not exceeding the height I need. If I overshoot I will need to find a way to file this surface down, something I don't relish. Still, it is likely I will need to do this and the maker of Bondic says that this is feasible with various standard methods.
I ran out of my first vial of the material, ordered more, but need to wait a few days for it to arrive.
BOUGHT KEY ON EBAY FOR THE ELAPSED TIME METERS ON THE 1130
Unfortunately, while it looked like it might be correct and was advertised as an IBM mainframe key, the key I received is probably for a cash register or other non-mainframe instead. I will continue to seek out the key which lets me switch the between CE mode and customer mode meters.
