    A quick question. I’ve recently invested in a new spring winder, of the Joe Collins style, and I’m delighted with it.

    My question applies to most types of winder though. How do you wind arbors with threaded keys, like alarm clocks? I am restoring a small Seth Thomas striking carriage clock which has one left-hand and one right-hand threaded spring arbor. I also have a couple of Metamec and Elliott movements with threaded spring arbors.

    My proposal is to make a slotted adaptor to take the key blade itself, as a tight fit. Any other suggestions, please?

    Phil I use the slotted adapter method as well. Work similar to the let down tools folks make out of a wooden dowel or broom stick with the slot.

    This is my method too. There are too many varieties around to justify making specialized let-down tools.
