I have a Seth Thomas no 2 with the no 77 movement, and this thing is really kicking my tail. Bought it at an estate auction a couple of years ago, went through the movement and replaced the weight cable with nylon cord as suggested by others here, hung it up(I don’t have a test stand that will handle a big weight like that), couldn’t get it going, and gave up. As I was eating dinner the other night, it got to bugging me, so I decided to take another crack at it. I checked my hanging job first, and discovered I was a few degrees off level, so I corrected that first and then went about trying get it in beat. People have said they are finicky, but I think that’s a gross understatement. I know beat setting basics, but I have some questions, and could use some pointers/advice that relate to this particular movement. My verge is the style in the pic but my crutch rod is nice and straight, not mangled like that one. I read a couple of threads on this, and there were mentions of ”bending the crutch rod”. I know that’s the method for many different types of clocks, and I’ve done that on every mantel clock movement I’ve built. The crutch rod on these is considerably thicker though, for one thing. Also, from looking at mine, and the one in the pic, it looks to me like the crutch rod is a friction/slip fit on the arbor. I’ve moved it in both directions(or at least I thought I did)enough to change the beat, on the first attempt a couple of years ago, and over this weekend as well. I did pull the movement out to examine the crutch before I started on Saturday, because I worked with it quite a bit the last time, and I was worried it might look like the one in the pic. It looked straight and true though, which also made me think it was a friction fit. I’ve been maddeningly close to getting it in beat, and it’s not far off now, but it’s no cigar. The only time I’ve had a perfectly even, measured beat, was when I got it so far off that it was backwards, and started on the tock instead of the tic. I‘m at the point now where the entry and exit are evenly timed, but the tock(exit?)sounds weak and faint compared to the tick. Thanks in advanc!
