Paul I had a couple of clockmakers like those and one was certified by the AWCI but yet wouldn’t take a clock apart. He would solder brass on instead of bushing the clock. I made a awful lot of money off those two. Some were a mess but hey I explained to the customer what I had to do but that their clock would be as good as new when I was done. I only had one or two that turned down my estimate but hey it is like I told them I am not going to reverse the repair of those two and then make it right for nothing.
