FINALLY GOT THE FINE ALIGNMENT DONE IN SPITE OF THE TURNBUCKLE
One of the earliest steps in the rotate alignment process is preliminary homing, where the typeball position is set approximately right. It involves accessing the carrier from underneath, with it sitting about 4/5 of the way to the left margin so that there is a hole through the mechanism underneath. A setscrew with a Bristol head is loosened, after which you turn the typeball from the top and then get back under to tighten the setscrew.
Because the turnbuckle system was not converging on a good setting, I decided to use the preliminary method as my final alignment instead of trying to change the length of the rotate rod using the turnbuckle. It only took a couple of tries to get the detent entering the teeth of the typeball right where I wanted it.
I also tweaked the tension adjustment for the string that activates the ribbon color shift, ensuring that it selects cleanly between the black (bottom) stripe and the red (top) stripe of the ribbon based on the solenoids that set the type color.
PRINTER CONNECTED TO THE 1130 AND EXERCISED ONE LAST TIME
I plugged the printer into the VCF 1130 and used my short hand entered program to test out its operation. It selected all the characters properly and shifted colors well. Once I was happy with its behavior and its condition, it was ready to go.
WRAPPED UP AND READY FOR PICKUP
I put on the case and wrapped it up in some padding as it will ride in the trunk of the museum manager who will come by to pick it up. I added a bit of cable lacing string to one lever that is otherwise a real pain to connect to the faceplate of the printer.
The faceplate of the printer has the console entry switches on it, but the wiring does not have a connector that allows easy detachment from the 1130 system. Therefore, before bringing the printer to me, the System Source Museum unscrewed the faceplate and left it with the system in Maryland.
A small rod runs from the right rear of the machine, when viewed from the front, to attach to a lever on the faceplate. This sets or clears the tab stop at the carrier's current column position. There is not enough room to get hands or fingers inside when the faceplate is being attached - at least not to grab that rod and attach it. A ballet with forceps and other tools is about the best one can expect. Often the rod falls down and requires removal of the typewriter cover to recover from that state.
However, I wrapped the lacing cord around the end of the rod, and taped it to the top of the printer top cover. That will allow whoever will reinstall the faceplate to hold the rod up and be able to get to it with pliers, forceps or whatever is needed.
