• We are aware of the performance issues with the forum. These are due to problems with Comcast's shared lines in the Columbia, PA area. On December 15, we signed a contract to bring a dedicated fiber line to the forum servers. It should take somewhere between 30 and 90 days to install. Thank you for your patience.

    1880 Ansonia Iron Cased Clock - Rating and Accuracy

    Sound advice, RC. But presumable is it a matter of trail and error, observation, patience and persistence to sort out. One thing that amuses me - no one has asked how the heck I produced the data for the graph! Certainly not by sitting in front of it for a week, that's for sure! Roy

    1880 Ansonia Iron Cased Clock - Rating and Accuracy

    It is great that there is so much knowledge out there. I refaced the pallets, and they needed it!, so I suspect the mainspring. David's recommendation to use a 3/4" x 0.0165" x 120" is a good one. I have another similar movement to do, so I will do that first, see how it goes, then come back...

    1880 Ansonia Iron Cased Clock - Rating and Accuracy

    Thanks very much for your feedback. Essentially, although there is room for some improvement, in principal one is stuck with the trajectory! So I won't bust a gut to try and get a flat line! People always laugh when I say that you have to make friends with an old clock to really understand its...

    1880 Ansonia Iron Cased Clock - Rating and Accuracy

    I recently overhauled the movement and all was fine until I tried to rate it. Actually it is more of a trajectory than a rating. Essentially it gains 4 minutes over the first three days and looses 6 minutes over the remaining four days - so it is loosing two minutes a week. My question is - is...

    English Georgian Double Fusee Clock - Repeating Mechanism

    OK thanks for that. The critical thing is that the star wheel must flip before the ratchet drops onto the snail. Otherwise at one o'clock the ratchet drops onto the snail still at 12, flips to one o'clock position and the tail of the ratchet rides over the snail. I was loosing about half a...

    English Georgian Double Fusee Clock - Repeating Mechanism

    Times were different! It would only have been the local clockmaker who took the hood off. You may have seen a hole going from the case into the door to the dial. This enabled this door to be locked. That was so only the master of the house was the only one who could alter the time when he...

    English Georgian Double Fusee Clock - Repeating Mechanism

    While restoring an English Georgian Double Fusee Clock I was intrigued to see that it it had a star wheel attached to the hour snail, and the hour hand had a clutch mechanism to enable it to be adjusted. At the time it didn't make sense. Then I came across a reference to a similar clock which...
