Well done Chris, that's marvellous; and it must be even more satisfying that you've been able to analyse the problem and devise a workable solution :clap: :clap: :clap: :clap:

PS how long before you can regulate the clock and then measure the run on the clock itself ?

cheers / Dave

raynerd:
Thanks Tim!

Dave, yes, it is a tricky one that. I`ve timed it over 10 minutes and using a standard stop watch started from the drop of the impulse pawl there is no clear difference in time. Now this in reality tells me bugger all, other than I`m not rediculously far out but to be honest, I could have lost or corrected the time keeping in my human error of starting the timer! Of course I`ll need to test it over hours, days and weeks for fine adjustments.

I think knowing or at least presuming that the time keeping of the clock is not rediculously out, I`m inclined to complete the clock, face, hands and case! Everything is so delicate and movements on one part, effect a movement or interaction on the other. It isn`t quite the same as a standard geared clock in that respect - it is much more delicate! It takes a good few 5-10 minutes for the pendulum to start to regulate itself alone after the initial human push...I`ve spent hours watching it now, making a change, waiting 10 minutes for it to regulate only to have it stop 30 minutes later and repeat!! I think I`m going to make it absolutely complete, mount it in position and then start to regulate and test the time keeping... when I get it running well I can then just leave it as I`m guaranteed, when I try and get it right in a temporary setup and try and move it to its permanent position, it`ll change!

I expect it`ll take me a a good few evenings to make the daisy motion and some temporary hands. Perhaps at that point I`ll clean up what I have and mount it uncovered in position and start testing. I`ve not done a shred of woodworking so the case making is going to be fun! I also need to purchase a proper clock time keeper. It is something I`ve wanted for ages and this is the first real time I can justify the money.

I`m woffling.... 3 or 4 weeks and we should see how well it runs.

Chris

PS. 10:45pm so that is now 12 hours 15 mins run time!

Looking good Chris. ( I like those little bearings !!! ) Keep up the good work, and check your PM's now and then.
