View Full Version : pallet cock glue?

Is it ever necessary to cement a pallet cock in place so that it doesn't vibrate out of location? I have a ST lyre movement with the pallet cock held by a single screw and a previous repairer had put some sort of resinous glue around the cock where it is attached to the movement plate. Seems odd, but maybe this single screw doesn't hold the pallet unit permanently with respect to the escape wheel? I have dissassembled, cleaned, reassembled the movement, and it seems to be working good for a week now, with no cement on the pallet cock. Why was this done?

Probly a "belt and suspenders" thing. Only place I can find for glue in a clock is to hold the case together.

I think Richard S is refering to the cocks that position the verge arbor relative to the 'scape wheel.
Usually, there's no reason to strengthen the adjustment unless somebody stripped the threads in the plate.
On better quality movements, the cock is located with steady pins and not generally adjustable.

Hmmmm.
Makes me wonder if the person who took this step had repaired the clock for a customer who consistently put it out of beat by moving it carelessly or starting it by grabbing the pendulum and giving it a good push. I can understand a repair person running out of patience on call-backs with some people and this may have been the step taken to solve the problem. At least the situation seems reversible, which is always a good thing when making alterations.
