Hey Folks,

I like to use Jeff Hamilton's Clockmaker's Apprentice CD Free Version to calculate mainspring lengths. My version got corrupt, so I'm looking for some one who has this program and could share it with me. I was hoping I could find this program in the library. Maybe I'm not searching correctly. Thanks!

Can't help with the software, but wonder as modern steel becomes so much stronger, if older equations become less accurate. The older, the lesser, sort of. Maybe the calculators I have used were older or springs were newer? Whichever formula I use, I seem to wish I could have bought a longer thinner contemporary spring. And, then there is the NOS, which is a throwback to a prior era of calculation.

Good luck!

His website says he is retired, yet still a member of NAWCC, so you might reach him that way or his personal email: jeff at thatdomainofhis dot com.

Perhaps his calculation includes a strength reduction to compensate for modern alloys and treatments? Wild pendulum arcs and caffeinated strikings are so annoying...So, I would be curious, as I just guess :)

Click on the beat book icon, and it will take you to Jeff's email (different than the one mentioned above) ;)
