Mainspring Clamp Not Fitting - NAWCC Forums
2024年9月15日 · I zip tied the mainspring and was able to remove the hammer assembly. As I thought, it was not connected to the front or back plates and therefore did not release the mainspring. After cutting the zip tie off, I was somehow able to get the C clamp around the strike side mainspring, at which point I realized per wow's point, the clamp is too large.
Zip Ties to Mainspring Rings - NAWCC Forums
2024年11月24日 · If you want to continue disassembly, you can probably do what most do when encountering a brand-new mainspring: Wrap the part containing the springs in a thick towel, hold each spring with a leather-gloved hand, then reach in with a wire cutter, and cut the zip tie. Hold on tight, and gradually let the spring unwind itself into the towel.

Mainspring too small for clamps - NAWCC Forums

I am trying to figure out how to install a new mainspring in a early 1900 Seth Thomas beehive cathredal clock.

Mainspring letdown - NAWCC Forums
2018年4月25日 · It stopped again last month right on schedule. Given how sensitive these clocks are to power fluctuations, and how slowly the mainspring turns(2 1/2 or so months per turn) it seems like this light viscosity is working fine so far with this relatively strong mainspring. The clock has been running 5 years since the service.
Mainspring gauge - NAWCC Forums
2009年8月10日 · Later this became known as the "US Standard" gauge. The edges have the usual notches for mainspring heights (based on the Imperial inch, but there is no obvious way to determine mainspring strength, except perhaps by barrel diameter using one of the three scales on the top left (which are Imperial inch scales in 1/64th and 1/32nd divisions).
