I can not get the strike train to remain locked so I can wind it, the count wheel moves tripping the lock lever. I have pictures

I,m not sure that I understand what you are asking. Is the strike not working properly?I can get the strike train to remain locked so I can wind it, the count wheel moves tripping the lock lever. I have pictures
I think your strike train is locking too late. That is, there us too long a delay from when the count blade drops into one of the notches and when the stop pin contacts the stop lever. That puts the count blade at the end of the notch. You will probably have to disengage the stop wheel and reposition it so the stop pin is arrested sooner after the count blade drops. The count wheel is attached to the main wheel, it is going to back up a bit during winding. Be sure to check the link in post # 11. This movement was designed without helper springs, but some sort of helper spring on the count lever is usually helpful. I am pleased with the straight wire spring shown in the link. I have also used brass spring wire coiled around the count lever arbor and anchored to the movement leg. It should work pretty well without the spring but I find it adds to the reliability.Thank you RC and shutterbug. I installed those 2 helper springs to try to solve my problem but the count wheel still moves when I wind it setting off the train I am at a loss on how to proceed, I have followed the set up instructions you have sent in your last post, looked at your new post of your movement and read Conover’s book on this, kindest regards , Peter
Yes, but the blade of the stop lever is very narrow. On this one the count lever blade is a dragger and not raised above the rim, much like a French count wheel clock. There really isn't a maintenance cam. Once the strike train is released from warning the slanted trailing edge of the notch in the count wheel lifts the count blade up onto the rim of the count wheel. When the blade drops into the next notch the stop lever stops the train. So the count wheel itself does what a maintenance cam does in other clocks.Do we know that it's locking on the stop lever rather than the maintanance cam?
Just askin'.
The count wheel is not supposed to move independently, but I have seen them come loose. My personal one was that way and I had to solder it. If it is moving independently it will never work. I'll see if I can dig up a picture.The count wheel moves independently of the main wheel both on the same arbor so when I wind it the count wheel slips and the trailing tapered edge of the gap raises the the count lever and thus the locking lever releasing the train, no matter how I have them indexed. I am still waiting for the other movement.
Mine took 42 half-turns when I wound it last week. With 25 half-turns I doubt that you will get a full week run, at least not without some serious slowing down, but the main problem will likely be that the strike will probably stop first which will allow the count wheel to get out of sync with the time. If you did in fact fix the problem, it should accommodate a full wind without something letting go. If it does let go on a full wind then sooner or later it will let go on a partial wind..............I can now wind it 25 half turns without anything letting go, according to a previous thread 40 turns are possible but mine let go at 30 before I did the repairs mentioned above. So I guess I could go further but I am being conservative......
