Hi, Folks:

I'm afraid its been a little while but its nice to be back. I am taking on a kind of Fun project just to see where it goes.

 

Most of you are familiar with the WESTCLOX Pocket Ben series beginning in 1917. These are commonly relegated to the "dollar store" category and as we see the construction degrade to ever-simpler manufacturing techniques over the years its not as though the label has not been earned.

 

My challenge is to disassemble and service a 9-67 Pocket Ben since it seems to be pretty close to the cut-off where rivets secured the plates rather than screws. Maybe sometime down the road I might even try drilling out the rivets and reconstructing by tapping the stubs for screws. Who knows. Right now my thought is that common lubing techniques for the gears are not going to work as many of the gears themselves are peened to the plate. Commonly accepted lubing guides are not going to apply here.  If anyone has suggestions for how I might tweak accepted standards and practices to account for this situation I would certainly appreciate it.  Please remember...I'm taking this on just as a challenge for myself and to stimulate discussion, so I acknowledge that these have never been huge candidates for servicing and rehab, 'kay?

Best Wishes,

Bruce

Thanks so much for the suggestions. 

I have watched "BUNNSPECIAL" before but have some strong reservations about his approach and techniques. I have a kind of rig to photograph my disassembly and did use the second link to load a book reviewing WESTCLOX that I had not seen before. Again..many thanks. 

Best Wishes, 

Bruce

Agreed.  I think my biggest issue is that when cutting corners I can readily picki-up

on what might be an unsavory practice. However, I also know that many hobbyists

like myself may not do their homework and consider his corner-cutting acceptable

practice. Of course, I will also acknowledge that not a few of many other YT

resources also may promote bad practice so there is plenty of blame to go around, right?

Best Wishes,

Bruce

This sounds fun.  I gather the main problem is getting the lube into the bearing areas.  I would tend to go for a lube which incorporates a solid lube such and moly, graphite or ptfe.  The solid lube will plate out onto the surfaces and do the lubrication once the oil has gone.  You could also consider dilution of these oils with say lighter fuel (which will evaporate to leave the oil in place) to get better penetration.   Autowinder reverser wheel lube?  Even a penetrating oil may work.  I would avoid greases and anything that has waxy additives (WD40!!), as these will just collect muck and seizure may follow.  Have fun!!

A forgotten part of a horological history is what you're quoting. I don't have an exact time frame but somewhere in the 60s through the 70s there were a variety of solutions that you could have. One of them was called miracle lube and there are a variety of other names for them. I finally saw material safety sheets for one of them and basically it was mineral oil dissolved in the rinse the final rinse your cleaning that is. So the oils in the rinse it gets everywhere in its stride Larry action pulls the lubrication in to all the cracks crannies and under the plates but it's worked.

Ms. very popular in high volume watch shops where there are doing literally hundreds of watches per week and they're doing M at a very bargain price because typically was wholesale work and go the jewelry store and jewelry store didn't care as long as it was cheap enough. For the most part all of those products are gone except they still have the clock one available. So if you're really desperate you could use something like this you get lubrication literally everywhere that it would evaporate and leave the oil in all the cracks and crannies. I assume because are still making the clock version there must be people out there purchasing it.

    • Thanks so much for all the tips! I tried both methods. I tried pulling the pins with two pliers but they wouldn't budge. I then tried the method shown in the clip but that was way too much effort and I was pretty sure the bracelet would not have looked right once I was done. I ended up getting a similar bracelet that's easy to resize but I'm glad we gave this a shot.
    • Yes. This machine can function in 2 modes, soldering and spot welding. The spot welding mode can be used for broken screw removal as well as repairing broken mainspring bridles. If your DIY one works fine, then there is no need to buy another machine. But if you are thinking of buying a new machine, I suggest you wait awhile because I heard that there is a new machine under development that in addition to the above 2 functions, has a 3rd mode that can be used to fill pits in corroded metal surfaces.
    • Thanks for clearing that up, I was just going by how it appeared to work in the few videos I had seen on line, especially comparing it to my own manual current based jobby, when they was showing it being used to remove a broken stem it seemed to weld as no solder paste was used. I will see if I can find the video. Did seem to work very well though, just trying not to buy it as my DIY one seems to work ok and i dont do enough to justify the cost, but ghen again we do seem to say that a lot Found the video It's on this sellers page https://a.aliexpress.com/_mtyFJxo You can see solder paste being used for the dial foot but not when removing the broken stem from the crown, it looked to me to be more like the flash from a spot welder which was why I thought it was based on a capacitor discharge like one of those spot welders used for battery pack assembly.
    • Well what do you say, if this is the work of a reputable clock repair it’s pretty poor. It is definitly needing a rebush. What Old Hippy has said holds true. The old bush out the hole tidying up and a new bush pressing in. I my self would drill the hole to remove the punch marks and make a bush to restore the plate but for that you need a lathe. Looking at the bush the condition of the pivot may also need attention, burnishing at the least to restore the surface. It’s not impossible to do it by hand , but will take care and time.
    • Thanks old hippy Its  shame really as it was purchased from a reputable clock repairer for not an inconsiderable sum. As you say it has been botched; even I can I can see that and I'm not a clock repairer.  Plugging holes sounds quite technical; what's involved please? I'm trying to weigh up how much of this I can do myself.  Thanks so far.
