Clock #1

I assume that this is the 'Wilding' version of the large wheel skeleton clock, which did indeed have french beginnings. Several members of Epping Forest Horology Club have made it and one of the last people to do so used a rayon filament to set up the finished clock, which would run for about 4 to 5 days. After completely dissassembly no faults or reasons for the poor endurance could be discerned........

However, after replacing the rayon filament with finest silk embroidery thread the run time suddenly became 12 days!....just one of those fascinating little happenings that keeps horology so seductive for us clock builders.

Hello Bob,

Fascinating indeed. I think I would have used a different word other than 'seductive' !

Thus 'seduced' by the idea that the finest silk resolved the problem attributed to rayon , would anyone in the EFHC care to repeat the test with rayon (filament), thus dispelling my thoughts that some other effect might have fixed the endurance issue?

Just curious, Bob.  

Personally, I would be concerned for the longevity of rayon versus silk in terms of environmental factors, none the least being UV.

Here in Australia we have lots of it scattered around. Don't ask me how I know.

Please forgive the digression, but I thought some members might be interested in this, about Bulle [silk ribbon] Suspension: **LINK**

No digression at all Michael, very relevant and interesting, I didn't know about that.

Just in case you haven't seen it Gerry, there is the excellent Clickspring's use of silk thread here:-

+1 thank you - I will have to make such an assembly jig after failing to do a good repair free-hand
