New Project: Bracket Clock By Bryson

Recommended Posts

This has taken me so long! The clock workshop has been closed due to covid, so everything ground to a halt. 
 

Anyway, I’ve re-assembled most of it for testing. Took ages to get striking adjusted so that that the gathering pallet locked promptly after the final strike. And also getting the run-to-warning adjusted. 
 

Still need to soak test the going train.

Will do. There is some pitting left on the steel parts of the striking work, but I didn’t want to remove much material (plus you won’t see it once the dial is on). The curved steel parts I put in a tumbling machine as they were very rusty. The clock had been kept somewhere damp (perhaps a garden shed). 
 

The fusee chains were also very rusty and seized, so I cleaned them ultrasonically in ammoniated oil-based watch cleaner. Then I soaked them in grease mixed with solvent which was then dried off. Time will tell if that is a successful method, but it’s a modern way of lubricating bicycle chains, so I thought I’d try it.

Some more photos, including the dial-side striking work. I only cleaned the dial-side components since they are not normally visible and I didn’t want to remove any material. I did however dress the screw heads as some of them were very marred. 
 

I’ve cased it now, but may take it back out to adjust the exact time of striking - it strikes at 5 minutes past, so I may un-mesh and slip the motion works slightly to bring it forward.

Its always nice that all screws are cleaned and polished. One thing I have noticed, its a good idea after fitting the steel pins for the ratchet wheels to bend them into an S shape this will prevent them from ever slipping out. You don't want them to give because the damage that will cause will be formidable.

    • Welcome to the group Stirky. You can search for just about every subject in the craft here. Don't be afraid to ask if you can't find the answer that may have already been covered ( some ad nauseum LOL ). You don't have to buy Bergeon to get good quality. There are many decent mid-range tools available that will last you a lifetime. Cousins would be a good place to start . Cheers from across the pond ! Randy
    • I picked up a similar amount of these jewels some years ago in a watch and clock fair. Every now and then they come in handy. This week I've got a rubbed in bombe jewel in the balance cock that is cracked and needs replacing. Very handy to have a vintage assortment of these type of jewels!
    • Great diagram with the teeth and pinion count. Simple way to reduce the speed of the hour wheel by the 12:1 minute wheel. Genius and yet so simple. Always good to reinforce the principal by what you have done in your drawing. Keep doing that. I had a drawing on my wall for years showing me this which is very similar to the drawing you have done. Here's a formula to work out the beats per hour of a watch movement. The movement's BPH is dictated by the wheel teeth and pinion count and the hairspring being vibrated to the correct BPH by finding the pinning up point on the hairspring using a vibrating tool.  The reason in the formula there is X2 on the top line is because there are two pallet stones.
    • So I just wanted to say "thank you" again.  The angle is the key bit it seems and yes, it did basically just fall, or float, back into position when I got it lined up just right. I had meant to add that now that I see how it goes in, I totally see how it came out in the first place, and that whomever cloned the original movement didn't pay much attention to the fine details around the setting or how it interfaces with the balance cock or the "rings" on the regulator and/or stud carrier arms.
