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.

As long as the chains are clean and all the links are loose when winding so they sit in the grooves on the fusee  that will be fine. You can't help pitting on steel parts, that's rust for you.

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.

      Hour Counting Wheel Assembly - Valjoux 7750

      By mcoulton · Posted

      Thanks for the information, its a big help. I'll try and pull off the pipe. I think I'll try using the Presto hand remover. Then I guess I'll try to fit the pipe into the hands(?) though maybe I won't have to as I'm putting a new set of hands on the movement.

      One of the problems with chronograph hands and whoever manufactured the watch would be that often times they are put on with considerable force. The problem with the amount of force they go on with is that often times when removed they disintegrate. So disintegrating hands unfortunately is quite common on a chronograph. With those lucky enough to have an account with were be authorized by whoever made the watch or the service center they would have a complete package of hands. so yes that does look like the brass tube of the hand that disintegrated.

      Elma Super Elite – Rusty Baskets Question

      By JohnR725 · Posted

      The unfortunate problem of the three jar cleaning machine. At least I assume it's a three jar machine. Classically with three jar machine the first is a cleaner and the second to be a rinse of the same type. Cleaning is a interesting process and it's not exactly cleaning and rinsed the entire procedure is cleaning. The cleaner is supposed to have chemicals to put things in the solution and things to make things right and shiny. The rinse continues to put things in solution and reduces the concentration of things in the fluid on the plates. Ideally you should have two rinses not one and alcohol. If you look at the modern cleaning machines you find typically now they will have a minimum of four jars or whatever. Often times the last one will have alcohol because depending upon where you live the rinse itself may not evaporate. So you have a final rinse of alcohol just to rinse off the rinse. Then the only thing I've ever seen on baskets would be this quoted below from something Omega has. But they are assuming that you have genuine Elma baskets and not a machine made in India from unknown materials. Although a lot of people are using the baskets from India I just don't know enough about them. Personally I've see in the baskets for other machines especially the holder which would be as it's implied below nickel plated where the plating wears off and eventually the brass will be etched away from the chemicals in the cleaning product. One thing I didn't see you mention was how long in the each of the baths? Usually for the cleaning products that make things bright and shiny. Time-limited approximately 4 minutes works really well. The rinses of less of concern it depends upon how much the cleaning fluid is dissolved in it though. You can download the specifications the cleaning products I like they have recommended times the final alcohol rinse is supposed to be relatively short as any time we mention alcohol and watches people get excited over dissolving the shellac. But typically with isopropyl alcohol it takes a little while longer and I've even used alcohol which I know dissolves shellac but I was just using it to rinse off the rinse so it was never a problem.

      Bezel for 1954 Rolex 6581 Oyster Perpetual

      By LittleWatchShop · Posted

      I think i am done. I was working withe two pieces, one was 316 SS and the other 304 SS. The starting material for 304 was thinner, so I opted for finishing it. Since I only have images of one of these watches, I cannot know the exact dimensions. The owner is not critical...just wants a working solution. I think this is it. It was quite the challenge to turn the inside  locking rim. An inside angle cut. Had to be damn close in order to have a snap fit. Frankly I think I just got lucky. Sometimes lucky is better than smart! The inside edge that interfaces with the crystal is an interference fit. This was on purpose in case my locking-edge cut was overshot...then the bezel and crystal would work together to stay put. Tens of hours working on this, and I learned a lot!

      Elma Super Elite – Rusty Baskets Question

      By TimepieceTinkerer · Posted

      I'm using: 2.5L Elma WF Pro – New Formula for the main cleaning 2.5L Elma Suprol Pro – New Formula for the first rinse Isopropanol Alcohol IPA 99.99% for the final rinse So far, all fresh fluids. I was also under the impression they shouldn’t cause rust, so I’m wondering if maybe the damage was already there and is just progressing now. Because my baskets came with the machine when I bought it pre-owned, I’m not sure if they’re original Elma or not. That’s exactly why I’m hesitant to buy a new set—I don’t want to end up with lower quality clones again if that’s what these are.
