Sam---if you can just give the od --the approx expanded length and the approx needed compressed measurement.---for instance I have one 3/8" od x.45 expanded length x .082 compressed length and the wire size is .011-------I dropped it three times measuring it but found it each time----I use a magnet and can find them stuck to it after scanning the floor in a sweeping motion----anyway try and guess some measurements that are close--unless you have the actual specs-----------Dave
Dave, I've done some measurements and can give you the following:
arbor diameter.079-- so I'll need something with a larger diameter. My original post of .375 was way off of the mark.
approx OD .158, that's the OD of the disk that retains one end of the spring. If you can't find anything that small I can always make a larger retaining disk, within limits. The clock is pretty crowded right there.
length: .5 inches max, .4 inches min. .4 puts me to the end of the arbor and then I have to add the thickness of the retainer and brass bushing that holds the spring in place so that will give me compression, hopefully not too much or too little, just like the 3 bears.
wire gauge: approx 72, most likely anything with a diameter of .020-.025 will do nicely.
I have worn out both of my shoulders swinging my magnet attempting to find that darn thing. My shop has too many nooks and crannies and I'm sure I'll come across it sometime in the future. In the mean time I've now ruined a pair of pants at the knees from crawling around on cement. Oh well, they were almost as old as I am. Cheeahs(That's with a Maine accent)
