Probably easier to get a complete new movement - but CousinsUK list it as discontinued. Maybe someone on here knows a substitute movement ? -
Any other thoughts on how I can get a replacement coil? Any “hidden” or unknown physical shops (in Australia or elsewhere) that might have them in stock (but not always online)? -
I discovered this last night when I printed my model, I'll try and tweak the design a little and re-post here
-
That could work - two blunt pressure points would spread out the force required in order to reduce damage, and two small pins should fit slightly angled through the inner coil of the spring. I was thinking about this while working on other chores and had a crazy thought when I saw a can of expanding rigid sprayable foam, but who'd want to have to clean out the barrel and spring after that? -
That's very observant of you, Nev & that the 4th wheel is from another movement & has been dished to fit does seem a more likely explanation. Thanks for the education re calculating the rate & spring frequency. In the meantime, spurred by your earlier comnent, I risked a further tinker with the balance spring, cleaning it, fully un-kinking the last few cms (I'd been worried about breaking it first time round) & pinning it at the very end. The clock now seems to be running slow when the regulator is in that position so some progress at last.....Many thanks, once again!
