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.

    • So I found what I believe is the setting lever screw! Am I right in thinking the screw next to the click is the correct one for the setting lever? However if it is, it doesn't fit in the hole which I believe is for it! I can get the lever to sit nicely on the stem and line up with a hole, but the screw only goes as far as the shoulder and stops. It's as though the hole is too small! The dial side has been disassembled by the way, the other wheels are in my tray
    • When faced with say a pocket watch bridge which is cracked, silver soldering to repair is often the only option (hopefully someone wasn't there before hand with soft solder). I can generally do this succesfully and tidily with a small torch and miniscule pieces of silver solder, but on parts which were mercury amalgam gilded the heat can have have a deleterious effect on the finish.   I keep wondering if there's a good way to refinish these - and despite having the needful items would rather avoid using the mercury process.   In the past for electronic work I've gold plated PCBs but this involved gold potassium cyanide solution, which also doesn't realy belong at home. I've read that there are now safer alternatives but couldn't find more detail (and importantly how similar are the results to amalgam gilding, since I wouldn't want to refinish the whole watch). Pointers would be very welcome (and yes, I know solutions containing gold won't be cheap!) Alan
    • The first one is an Unruh max stake for pushing out staffs
    • Ok so with the great answers for my previous question may I ask what these two attachments are used for. The one with the red knob is I assume used for hand setting the seconds hand? Jon      
    • According to Cousins site I need to look at document G22 as I think I need an ATGB at 304 but I cant find this size in G22 doc. The last thing I want to do is order the wrong one😳  Unless I cant see the wood for the trees 😆 I could be looking at the wrong style, I assume its classed as Round plastic Armed  https://www.cousinsuk.com/product/wide-ring-gold-atgb
