Hey folks,
I need a hand figuring out the mystery of the hour meter wheels in a proofmeter I am trying to repair. I know... I know......, but I can't pass up a challenge.
I have managed to disassemble and assess the workings. Found the one 'plastic' gear stripped in a section, but got the brass gears freed and cleaned up. Repaired the gear with epoxy and filed new teeth.
Got the hour wheels off the rusted shaft, cleaned shaft up and now trying to reassemble the wheels. For the life of me, I can't figure out how they function. Obviously, the first wheel has to go around a complete rev (1,2,3....0), then drive the neighboring wheel only one 'click', and then keep rotating for another '10'...etc, etc. I have studied the relationships for hours....but can't quite make it come together. Guess a big sticking point is understanding the thin plastic 'hooks' that point in opposite directions that are part of the black disc which houses the tiny drive gear between the number wheels. The tiny gear seems to be driven by a slot in the wheel to its right, and drive the wheel to its left. I see there are two different heights to the 'pins' on the tiny gear ...which makes me feel the slot will drive it only when engaging a high pin, but not at some point (? when the 'hook' meets frame)
In any case, I tried to search here....found some [u:c0c4affcb2]old[/u:c0c4affcb2] threads on the subject, but only one from member " bg " that referred to pictures and explanation of proofmeter workings....but alas, could not find the pics or info.
SO......if anyone out there can tell me how to arrange the wheels and hooks to make this work, I would sure appreciate it. :?
THANKS!!!
