and a few followups. There were some very good and sane cautions about what I did, but in practice they turned out not to be an issue. I've been using this spring winder many times a week for a while now, and it works great. Another plus is that the easily detachable tap holder does double duty as my let-down tool, and the knurled chuck makes it VERY easy to control the speed of the let down. If I can build this thing, YOU can.
If you have any questions or want some more specific pictures, let me know.
Right on, Willie! For me it's almost as much about the tools as it is about the clocks! I built my spring winder from scrap parts and about $10 of miscellaneous bits from the hardware store. The tool was the easy part - the sleeves were another story. Finding the right diameter tubing from which to make them can be a bit challenging.
