replacing a battery powered mechanism

Posted: Mon Apr 19, 2010 1:16 am     Post subject: replacing a battery powered mechanism

Hello all
I too have a clock that needs a new mechanism. I think I have found everything I need but one item. The clock is hand made and the old mechanism had about a 5/16 shaft diameter and it had a small threaded bushing that went around the shaft and held the mechanism in place. The hole through the clock face is 1/2 inch diameter so it needed the screw on bushing to fill the space around the shaft and the clock face.

I only see hex nuts to hold the mechanisims in place. So this means I have to fill the area around the mechanism shaft or I will be off centered. Am I just missing this screw on bushing on the klockit web site or do I have to look for another bushing or a 1/2 shaft diameter mechanism? Thanks kwg

The klockit movements come will all the mounting hardware, and it sounds from your description that a new quartz movement should fit right in.

If you need a larger hex nut they also supply one , or you could epoxy a brass wahser on both sides of the dial with the correct inside diameter to take up the slack.

I would recommend purchasing a large size brass washer from a local hardware store (maybe 5/8" O.D. - - Maximum 3/8" I.D.). The washer will cover the 1/2" hole through the dial face, yet allow you to make use of the hex nut style movement (as it will also provide surface for the hex nut to secure against). You should not need to afix this washer with adhesive (as the hex nut will hold it in place). Also make certain to use the provided rubber gasket (included with the movement hardware) behind the dial to give the movement some grip. As amrad suggested, it is probably not a bad idea to glue another washer on the backside of the clock face (just to limit the amount of room the movement shaft can shift within the 1/2 hole). Make certain to factor for washer thickness when determining movement threaded shaft length for your replacement unit.

Hello guys
Thanks for the information. That was pretty much what I was thinking also if I could not find the appropriate nut. This really looks like a fun hobby. I wish money were not so tight. I see klokit has some really interesting kits. Maybe some day I can find the money and time to put together some clocks for personal therapy and family and friends. Thanks again. kwg

Forgot to mention - - Klockit movements include all necessary hardware for the movement. The cap nut, open nut (for second hand option), hex nut, small washer, and rubber gasket are standard staples for every movemet hardware pack. This means that you should only need to source the large brass washer separately (at a local hardware store).

The clock building hobby is quite theraputic (but mostly just good, clean fun!). If you should have the resources in the future, I highly recommend giving it a whirl!
