Hey Bob i got it.
I thought about what you were explaining and i think i miss understood about the time train cam, i was thinking you meant the cam up in the right top that spins and runs the time train for the quarter,half three quarter and hour. That is held on with a set screw.
This morning i was studying how all this works for the hundredth time lol. I was watching that cam behind the hour snail, thats what i call it its the thing that the arm drops on to let the clock know what hour to chime. well right behind that is a cam with three short lobes and one larger one. the larger one is to tell it that is is on the hour. This cam raises a v arm that triggers the chime train and the cam in the chime train has different size cams one for the 15 minute next for the half hour and three quarter and hour, thats the one i thought you were talking about.
Any ways i watched the cam behind the hour snail and noticed the v arm was dropping five minutes or so before it should. Then i thought, i bet thats the cam Bob is talking about. so i held that cam with twizers and moved to minute hand backward and low and behold it sliped on the shalft so i kept moving the minut hand backwarn intill i got it to drop at the right moment. That cam is pressed fit so i must have jarded it at some point moving the minute hand backward some and causing the cam to slip out of time.
Thanks Bob for having patience with me, everyone else i talked to said i was crazy to even try working on a german clock not ever done clock work before. They all said i would wind up throwing it away. I can say i almost gave up a few times expecualy when i was trying to get all the time train stuff back in time and a couple heart attacks.My back is also so bad i can only set and work on it a few hours and then rest sometime a few days. I really enjoyed doing this project alot.
Now i have a new project, its a Ingrahman Mantel clock 8 day movement.it says made Nov 11 79. Im thinking its 1879. looks to old to be a 1979.I dont think i will do anything to the case its not that bad but the movement need all new bushing.
I ordered a hand KW reamer kit From Mile High clock and cutting and smoothing broaches and a few other thing i may need. I think its going to be interesting also. A new thing to learn or mess up never did rebushing a clock either lol.
I’ll send pics and one of the Grandfather clock finished also.
Thanks again Bob
