Author Topic: Clock dissection help?  (Read 1087 times)

I have acquired defunct clock that is more scrap metal than anything else. I'm trying to salvage the gears within, the largest of which measures about 2.5 in (6-7 cm). These are connected to the springs. The rest of the gears are connected to shafts which I neither want nor have use for.

How can I remove the gears from the shafts/springs without hurting the gears?

I have access to: soldering implements, hacksaw, power drill and bits, hammers, screwdrivers, socket wrenches, monkey wrenches, wire cutters, bolt cutters, pliers of many persuasions, and files.

In addition, can anyone recommend a degreaser?

Word of advice first : make SURE the main spring is UNWOUND! - there is quite a bit of energy locked up in a clock spring, pulling the clock apart with a wound up main spring is a good way to get a nasty surprise, and possibly an injury (it's happend to me before, I speak from experience...). Wink

The shafts on the gears can be tapped / pushed out - have a search of the forums, there's one or two threads that describe this.

For a degreaser, any petroleum based solvent will work (petrol (gas), white spirit (paint thinner / turps substitute), paraffin, WD40 etc.) To remove any left over traces of grease / oil, use soapy water or methylated spirit (methanol / camping stove fuel). Smiley


As for how to take it apart - it depends on how it's held together in the first place...  Wink

Thanks very much. The advice on the springs came a bit too late; I gave myself a rather nasty shock when they popped free from the housings.  Roll Eyes I still have all of my fingers, so no harm done.

..i made an auto-rig that uses pliers in reverse to get the springs out..it never works well but it sure was fun making a robot.
