    Way back in 2012 I posted this Wurth clock number 10566:
    Post Your W. Würth & Co. Clocks Here

    When I received it the crown was damaged with one screw broken off in the front plate, and the other bent over.

    Of course this is a specialty screw with non-standard threads. I couldn't find replacements so the clock has been on the shelf waiting for attention.

    I finally decided I'd spent enough on machine tools and it was time to make the screws myself. How difficult could that be?

    Let us know how it goes!

    Well the result was in the last picture above!
    screwb.jpg

    This was my third attempt and it only took about 3 hours. Part of that time was making a rigid setup to cut the threads

    and grinding my own tool (both with expert advise from Jerry Kieffer) after breaking the carbide shown above on my second attempt.

    Here is my final screw (right) with an original:

    and here are the threads:

    It is slightly longer than the original but it works fine. Now I have a good reason to dissolve the old screw bit from the front plate and service the clock.

    I have another Wurth clock that needs a pair of these so I'll be making a few more. Hopefully I can get them right on the first try.

    Eric -

    Will you be making a few extra? Not sure who in the near future might need a few, but if you're willing and want to think about making your services available down the line, I'm sure it would be appreciated.

    Make the crown, too! It seems there are a few clocks out there needing it. Mine for one.:)

    I'll certainly be making a few more if only for the practice. I'm still trying to figure out the best way to do this.

    These screws have the same thread as the four tiny ones that hold the suspension guard rings in place.
    Snapshot_201901018_120002.jpg I could probably make a few of those too once I get better at it. Much more than that and I would have to start looking for a custom made die $$.

    I have several other brands missing the various screws which I also want to sort out. Some of what I've found in place of screws has been pretty horrible.

    The crown would be fairly straight forward cutting and filing some brass plate. The finials would be the challenge.

    Nice job Eric. In another fifty years from now if they, have to be replaced on yours or another similar clock, one would be hard placed to decide if they were original or not.
    Now for the extras that others may need....

    I did make a couple of extras along with the two that I needed. Not a perfect match to the original but pretty close. I'm happy with them.

    These four took me a couple hours to make from 2mm 12L14 steel. I could probably make more now that I have the procedure figured out.
