With a pivot size of 1.45mm would a bushing bore of 1.6mm be about right so that no reaming or smoothing would be required? bushing 2.7mm O.D x 1.4mm HEIGHT x 1.6mm BORE. Plate is 1.4mm

You could try it. Bushings compress as they are pressed into their holes, so your inner hole will be smaller after installing. Bushing work is a lot of trial and error, and often the ID has to be revisited after the bushing is installed.

Consider a bush with a slightly smaller diameter hole than the pivot and open up with broaches or reamer to fit otherwise if the bush isn't completely perpendicular to the plate, although there looks to be clearance when you have the clock apart, you will/might run into uprighting issues. Within reason, it doesnt matter how much bigger the hole is (within reason!!!) as the pivot will be forced against the wall of the hole when in use. as always, it is depthing (mesh) that is important. Hope this helps.

Lego,

It is normal practice, in my shop, to hand fit every bushing. Also, every bushing needs to be tested before final assemly. I just outlined this on another thread.

You can try the bushing on the pivot before installing in the plate. It will probably be a little too sloppy.
