what clock bushings do i need for a WUBA movement in a Warmink weighted wall clock?
Not sure on than one
I am thinking about buying a bushing tool. When they are described as for the KWM or Bergeon systems, does that really mean that one can only use that type of bushing with the same type of tool, or that either type of bushing can be used in either type of bushing tool? Also, what are the real advantages of a more sophisticated bushing tool ($1,000.00) versus a clamp on type ($150.00)?
bergeon and kwm systems are coompletely different. NOT compatible with each other. Kwm bushing system is what we use here. The kwm system uses smaller diameter bushings which many times helps when the pivot hole is too close to the edge of the plate. Also, less material is removed in order to fit the bushing vs bergeons larger diameters. We use The Elma KWM bushing system in the shop. These machines are valuable in their own right.
Superior to the hand bushing tool, it will hold the plate snug, the hole will be reamed true. It makes bushing a clock movement a breeze. Then on the same machine, you swap the reamer and you can then press the bushing into the plate without ever removing it from the machine. We stock all KWM bushing sizes.–Bob
Hello, I have a 2.25mm OD bushing I would like to replace. The pivot diameter for this bushing is 0.64mm. Is the proper bushing L47 for 2.0mm height? How small is the opening prior the reaming? Thank you.
L47 is 1.9mm tall, so this would be the proper bushing for a 2.0 plate, L47 takes a reamer #4 on the kwm system. the id in the bushing before reaming is 2.4mm. When the bushing gets pressed into the plate, this ID may shrink slightly, so cutting and smoothing is a must. –Bob
Thank you.
I’ll need to find something with a smaller ID….
what does your pivot measure out at?
The L33 is 1.9mm plate thickness and 0.6mm id. uses reamer 2.
Hello! We are working on a Howard Miller Millenium Grandfather clock, and believe the poly bushings on the escapement/pallet arbor are worn. Very small black rubber. Would you have that size range of bushing….and how do we measure the pivot diameter, as well. Thanks…Alex
