      I’m on to my next clock, another 400-day but standard size Schatz 49. I hope I can explain the problem I’m having since I’m not sure I’m using the right terminology. The problem is with the first wheel. The arbor is turning, but the wheel is not secured to the arbor. So, in turn, it allows the mainspring barrel to spin freely. Is this fixable or do I need to find a replacement wheel? I hope I’ve explained my problem well enough.
      Thanks,
      Andrea

        Hey Andrea,

        Sounds interesting and I’m sorry I can’t offer any info, being a watch guy and all, ya know :D
        I’ll take a wild stab in the dark and offer this guess…. Would the gear happen to be threaded onto the arbor, kinda like a safety pinion?

        If you could post a beautifully clear and highly detailed photo, I would be interested, as a budding hopeful, to see the issue in technicolor 8-)

          Unlikely the wheel is threaded but they can often be riveted back on to the arbor. A photo would help and we can guide you from there.

            Here are a couple of pictures. Thank you for your interest in my problem.

              Ok, if you look at the second picture where the arbor comes through the wheel you can see where the pinion was turned down and then riveted over to hold the wheel. You need a punch that will fit in punch those little “petals” if you think of it like a flower and spread the material to hold the wheel on. Dont be just tempted to solder it in place as this is the intermediate wheel, the first wheel after the barrel and is under a lot of pressure from the barrel.
              Hope that helps,
              Paul.

                Thanks, Paul. I appreciate the detailed and patient explanation. So, it looks like that will be my next tool purchase. Can you give me any advice on that? Is that what a staking set is used for?

                  There will be punches in a staking set and if you are serious about clock repair a good staking set is certainly a very useful tool which should be somewhere near the top of your shopping list.
                  In Bobs videos he shows the K & D Inverto sets which are very nice but very expensive. The Japanese sets are very good and you can find those much cheaper.
                  Keep your eye on this one – Staking Set

                    Thanks again, Paul. I see eBay in my future! I’m sure I’ll be asking more advice when I have tools in hand.
