Hello folks!

I received this anonymous WW style lathe a few years ago, and I'm just now getting it into working order for some watchmaking-adjacent projects.

I've run into two problems: first, with the headstock and second with the pulley set.

I have heard it's good to clean the headstock, so I have removed the dust cover rings on the rear outside, plus removed the pulley set screw and loosened the two interior knurled rings (you can see in the photo that the left interior ring is completely free of its seat, whereas the right side is not). Even without the set screw, the pulley is still firmly attached to the shaft. Light tapping does not move it and I don't want to risk damage. Is there another place I should check for fasteners or other disassembly steps, or should I continue gentle percussive force? I have noted that others require tapping to remove the spindle, but I don't want to go whacking things at the wrong time.

 

As for the external pulley transmission, the problem is with the lower crossbar. It looks like you should be able to loosen the handle, move the bar to select your pulley, then tighten it. It does indeed do that, but one half of the bar is very tight even with the clamping screw completely removed, and the other half is so loose that the clamp doesn't work (even after I really crank on it hard). Is this a case of equipment failure or user error?

 

Thanks all!

-John

Look up my videos on YouTube. I have a ton and some on lathe work JD Richard

I'll second that advice for any other folks, you've really got a good range of information there! 😉 

 

I actually used your method of making belts with fishing line, to avoid snapping the connection on the plastic ones or experiencing excessive vibration with other methods. Mind you my belts were rather too large, but that's a minor detail 😬

    • it would be nice to have the exact model of the watch the or a picture so we can see exactly what you're talking about. this is because the definition of Swiss watch could be a variety of things and it be helpful if we could see exactly the watch your dealing with then in professional watch repair at least some professionals they do pre-cleaned watches. In other words the hands and dial come off and the entire movement assembled goes through a cleaning machine sometimes I think a shorter bath perhaps so everything is nice and clean for disassembly makes it easier to look for problems. Then other professionals don't like pre-cleaning because it basically obliterates the scene of the crime. Especially when dealing with vintage watches where you're looking for metal filings and problems that may visually go away with cleaning. Then usually super sticky lubrication isn't really a problem for disassembly and typically shouldn't be a problem on a pallet fork bridge because there shouldn't be any lubrication on the bridge at all as you typically do not oil the pallet fork pivots.  
    • A few things you should find out before you can mske a decision of what to do. As Richard said, what is the crown and all of the crown components made of . Then also the stem .  The crown looks to have a steel washer that retains a gasket. So be careful with what chemicals you use to dissolve any stem adhesives or the use of heat. You might swell or melt the gasket unless you are prepared to change that also . The steel washer maybe reactive to alum. Something I've just used to dissolve a broken screw from a plate. First drilled out the centre of the screw with a 0.5mm carbide . Dipped only the section that held the broken screw in Rustins rust remover. This is 40 % phosphoric acid. 3 days and the screw remains were completely dissolved, no trace of steel in the brass threads. A black puddle left in the solution.
    • I suppose this will add to the confusion I have a roller jewel assortment. It lists out American pocket watches for Elgin 18 size and even 16 size it's a 50. But not all the various companies used 50-50 does seem to be common one company had a 51 and the smallest is 43. American parts are always interesting? Francis Elgin for mainsprings will tell you the thickness of the spring other companies will not even though the spring for the same number could come in a variety of thicknesses. But if we actually had the model number of your watch we would find it probably makes a reference that the roller jewel came in different dimensions. So overlook the parts book we find that? So it appears to be 18 and 16 size would be the same sort of the arson different catalog numbers and as I said we don't have your Mongol know which Log number were supposed to be using. Variety of materials garnered her sapphire single or double but zero mention about diameters. Then in a section of rollers in this case rollers with jewels we do get this down in the notes section Roller specifications but of course zero reference to the jewel size. I was really hoping the roller jewel assortment would give us sizes it doesn't really. But it does show a picture of how one particular roller jewel gauge is used  
    • Seems to still do it through my mobile data, I use an android phone almost exclusively, but I'll double check it. Thanks mark Strange, I'll try my laptop that utilities edge. I've been on site half hour since I got home, it hasn't done it yet. Thanks John
    • At work, I'm on MS Edge, not through chose, on my phone, chrome, no issues with either.
