press on plate

[arron]

Good day,

before i break a clock wheel shaft, i thought i'd better ask if folks have ideas for how to press this small plate back onto the wheel shaft.  it is off of an hermle 340-020.  i pushed it on by hand as far as i could get it.  i tried using tweezers on the plate to ride to the sides of the shaft so i could get even pressure but it won't move at all.  wasn't sure if i should give the tweezers a few taps with a small hammer.  i definitely don't want to break that pin off.  any ideas.  thanks.  arron.

Hi  The gathering pallet can be firmed up with a light tap using a hollow punch, the shaft should be tapered, Just enough to stop it moving as it carries no weight just steps the rack back up to the starting point.

thanks for the suggestion.  i'll try it.  have a nice day.

Yes agreed with watchweasol.  Hollow tap.  Removing it, i disassemble the entire movement and leave the pivots with gathering pallets for last.  Then i lightly tap it with solid tap on the top of the pivot
