    Default 10EE Tach Repair: before and after

    The tachometer on my 1942 10EE had the glass and hand missing, plus the dial was destroyed, as you can see here:

    I spent most of the weekend rebuilding it:

    Cal sent me a photo of an original dial, which I digitally cleaned up and then printed to size on paper, which was then glued to the dial plate. The original arbor had a pivot broken completely off, but fortunately, I also dabble in antique clocks and so could remake one. The new "glass" is acrylic. I spent some time buffing out the worst scratches in the bezels. Everything else was cleaned and lubricated. The original hand was white, but I found this red hand from a quartz clock in my box of scrap clock parts and adapted it. I like it better! Very visible.

    Just for reference, here are the inside parts of the tach:

    Very nice, the red hand does stand out nicely.
    The lathe is in good hands.

    It looks great! How durable do you think the printed dial will be? There's a guy in here in Tucson that does photo engraving on metal, if you wanted something like that. He did some very nice replacement round-dials for another PM member several years ago.

    Can't be sure, but with a dab of silicone sealer around the front glass and a good home-made gasket with sealer around the outer bezel, it shouldn't see any leaks. And, of course, nothing touches it. If it ever starts to fade or look bad, all I need to do is print another one and replace it!

    You can have a silk screen (now actually polyester) made from a photo. I made a lot of locomotive speedometer and load meter dials that way, but I had the local GE shop paying the bills. There was a period where the GE shop had trouble getting dials from the GE factory for some reason. For a while I even put the GE logo on them until the manager got worried that someone would object, even though they were being made for one of their shops, so I painted it out. Great work on your tach.
