    Last week, I was able to buy a circa 1848-1850 Boston Clock Co. Aaron D. Crane Patent Twelve Month torsion clock at a GARAGE SALE!!! You can see photos of it in the "Your Newest Clock Acquisition" forum on this site. My clock has a broken torsion spring that I'm trying to replace. It is about 10.9" long by .02" by .003". Do any of you have ideas as to where I can obtain a similar torsion spring or have one made?

    Fo those not familiar with Aaron Dodd Crane, he was an American clockmaker credited with inventing the torsion clock, for which he received a US Patent in 1830.

    I can't say I've heard of springs that long. I would call Chris Nimon at The Horolovar Store and see what he has to say.

    Thanks Kurt. I spoke with Chris this morning. He can supply the correct length, but not the correct thickness.

    What thickness does he have? With some effort, maybe it could be thinned.

    Chris said he could provide my required length with .005” x .005” spring. That would look good, but would be too narrow a profile for the clock to operate properly.
