I will need a faceplate to make modifications to a specific watch case to fit the movement or just to broaden my capabilities. It must be DIY of course :) Looking for simple designs like these:

But it is not clear what the cranks at the outboard of the clamps are used for. Are they necessary?

"But it is not clear what the cranks at the outboard of the clamps are used for. Are they necessary?"

They are like small toolmakers clamps and are used for clamping thin plates.  The slots in the faceplate allow easy positioning of the clamps/job to be turned.

If you know how a toolmakers clamp works it should be self explanatory.

Hehe, i only know that it is used to turn plates and such. Never used one before.

I just think that the screws at the back are to tighten the workpiece. But those other screw??? What they do?

Here's one off my Boley lathe.  

You adjust the clamps until they gently grip the part that you wish to machine.  Once you have positioned the part correctly, you tighten the knurled nuts at the back of the plate to grip the part really tightly.

AAhhhhhh!  Now i got it :) That nut at the front is to adjust the clamp to the workpiece thickness, that the clamp will stay parallel to the faceplate! Thank You for the excellent pictures. Now i can see that spring as well. :woohoo-jumping-smiley-emoticon:

Could You please measure me the width of the long holes in the plate. Or what is the thread size of screws? Thank You!

      What's your thoughts on this Rolex Sea-Dweller, ref. 16600, calibre 3135 project?

      By VWatchie · Posted

      Well, my fundamental stance is that I want to go in and out without leaving any trace other than a shining, perfectly running movement. So, no scratchings on the inside of the case back lid, no marred screws, no debris, no fingerprints, and so on. That is, my goal is to make it impossible for the FBI to track me down. As a professional, I suppose you might want to keep track of returning watches, but as @JohnR725 mentioned, we can keep detailed computer records without marking the watch at all. That may not be true for every watch, but luxury and COSC-certified movements do have unique numbers. John also says it’s best to leave no sign you were ever there, and I couldn't agree more. Now, suppose the Sea-Dweller I'm working on is one day scrapped, and you want to sell the case-back separately (perhaps the case was destroyed in a plane crash). Then the scribbles on the inside no longer reflect the current movement inside the case. Also, the engraving will likely halve the market value of the case back. It had been "sleeping" for about a week and a half. Yes, the "debris/old lubricant" theory is my hypothesis as well! It will be interesting to see what I find once I have time to start disassembling the movement.

      Help with repairing a quartz clock

      I've repaired a few of these, having some success with stripping and cleaning the mechanism.  They are so cheap though, its hardly worth the effort in many cases.

      A lathe with indexing that won't break the bank?

      By SwissSeiko · Posted

      Id love to see how he has the output shaft mounted to this setup, as I have the same rotary stage and stepper in my build.

      Broken watch stem in watch crown

      By Poljot · Posted

      If you see at least one thread protruding, or even a half, then you may have a chance using this "tool", but don't squeeze hard. Lot's of patience, and if you notice any signs of loctite or other adhesives, then apply several drops of acetone on top of broken stem. Use heat (hair dryer) also. You should be able gradually turn it counterclockwise, just like i did on this broken Timex stem, which was glued with something like nail hardener. Then you can use an extender to save your broken stem. https://m.media-amazon.com/images/I/513DVvkfW5L.__AC_SX300_SY300_QL70_ML2_.jpg   You can also try cutting a small grove / slot on top of the broken stem to use 0.7mm flat screwdriver.   Depending on the Crown material and Stem material, you can try dissolving the stem.
