Thread: constant force springs for wood gear clock

Wanted to see if I am able to post a pic, she's not done yet, I still have to complete a couple of parts and tear her down for finishing....

I have come to a similar conclusion, running out of wall space and looking at constant torque springs to run mantle clocks. Unfortunately that is as far as I have got!
I have built an electromagnetic driven clock, one of Dave Atkinsons designs, woodentimes.com, it does work well!
Sorry, don't know how to work out size of the spring required - but keen to fine out too!

Chris, thx for the response! Looks like we are in the same boat, lol, maybe someone will help us out. I love what Dave has done, at least n theory, very compact and only requiring a 9V battery, in fact, that is what got me started on the whole kick of an alternate to weight driven clocks. Up to this point I've been building Clayon Boyer clocks, what a gem for clock enthusiasts. However, I'm ready to branch out and start designing my own clocks.

anyone have any suggestions?

I've just got one of Clayton latest designs, the epicyclic, to learn about constant torque springs, started cutting some parts, the only snag is that the constant torque springs this side of the pond are different to his spec spring. I know I could get one sent over, but postage costs end up outweighting the cost of the spring. So re-designing a few aspects to cope with metric springs and the torque values are not identical so playing safe and over specing the spring!
I too have built other folks designs, mainly Dave's and now want to design my own..... Tis a sad world!!!!!!

Happy New Year to you!

Chris.

Like your Inclination, it is on my list to have a go at, I really like the design, - if I can think of somewhere to put it that is!!!!!!!

thx Chris! It's a variation on his original plans and a pic I saw of someone else's. I so love the epicyclic but I'm a little concerned about the size of the wheels, I cut all of my clocks on a scroll saw... Keep us updated on your build!
