I'm having problems with a Sessions movement that mounts with wood screws. The movement runs great on a test stand, with everything snugged down properly as it should be, but once I install it, I cant get it right. The front plate has 4 screw mounting tabs bradded onto it, and it mounts to the case with 4 short wood screws with a thread length of about 3/8". The problem seems obvious, but I haven't had any luck solving it. What appears to be happening is that when the screw are tightened, it distorts the plate and puts the movement in a bind, and it won't run. All of the screws are straight in the holes, nothing stretched or going in at an angle, and I've pretty well used up my automotive and construction bags of tricks. I've tried all of the combinations of tightening sequences, cross-corner, top first, bottom first, left and right first, and none of it made any difference. When the movement is mounted tightly in the case, things are in a bind, and the tighter the screws, the worse the bind. I don't have much experience with clocks, and I know they don;t have to be cranked down with a breakover bar and a cheater pipe, but given the short length of the screws, I would think they would need to be at least a degree past snug, to be properly braced for tension during winding ans so on. The one thing I haven't tried is loosening all of the nuts on the back plate, tightening, the mounting screws and then tightening the nuts back down, but I don't have much faith in that doing the trick. I can get it to run for brief intervals and at varying degrees in and out of beat by loosening different combinations of mounting screws and plate nuts, but it just doesn't want to run with everything snugged down. Does anyone have a good trick up their sleeves for this? i searched the forum, but didn't find anything on tis particular issue. Thanks!!
