    Any recommendations for a miniature wheel or gear puller for use in removing stuck on clock gears. could use a stake set but i would like to limit the use of hammers on brass clock movements if a puller would work . Thanks. Carl

    If you are referring to pulling a clock wheel off of it's hub I would recommend a split stake, hollow punch and hammer after a small bit of filing to remove the brass that has been displaced to hold the wheel. I would be afraid of bending the wheel if using a wheel puller. I have a few different pullers... mostly the ones you see in the clock catalogs but usually only find a use for them to remove stubborn hands.

    What gears in particular are you thinking of and what are they stuck to? For removing cannon pinions and the occasional pressed on gear or part such as a gathering pallet I use levers. I made my own from a set of cheap screwdrivers that I annealed at the tip and then bent into a crowbar like curve. Then I polished them. Using levers brings you in very Close to the arbor you want to separate the part from so no risk of bending. Just make sure that the other end of the arbor is supported in a good way, and that you aren't pulling on anything sensitive. Plates can get bent in this way if you are not careful.

    Best of luck!

    Does a tool like this work? This is from an article in the NAWCC Bulletin October 2000

    Any tool that leaves less marks is good.

    Thanks for all the great advice the parts that I want to remove and then reinstall are the locking plate, gathering pallet and any other "stuck" gears on a New haven triple plate chime movement that I want to clean and reassemble. I have used the lever method on watches as well as the stake and punch method so I guess I may have all the tools I need to proceed. Does anyone know if these parts were hand pressed on when the clock was built or were they driven on by machine? Thank you all again. Carl

    I don't know hoe they were originally installed but they can certainly be installed using a bushing machine or a small hammer and brass tubing.

    I use the hammer and brass tubing method. Be sure to support the pivot on the other end of the arbor or you risk to bend the back plate and may get excessive end shake.
