    I'm not sure if anyone else did or not today but I worked a guy who made his key with a 3-d printer. I've done it all now. 73 Rich

    I repaired a cutterhead suspension box for a lathe similar to the one in the post above (mid 60's type).

    A long-time friend of mine in Portland, OR called in a panic Friday because his stylus heat had stopped working.

    We spent an hour on the phone trying to troubleshoot the problem and, after trying to solder a toggle switch over the bad switch contacts, he started blowing fuses and burning heater wires open.

    My advice? Drain the oil out of the damper and send it here. He's the third owner of this lathe and I knew that it had lived a hard life before. This box has been iffy for a while. Unfortunately, the leaf switch parts are unique. Finding replacements would be difficult and time-consuming so I'm going to just beat it into submission.



    This is how it came in.

    Over the eons, the contacts were brutalized as desperate people tried and get them to work. Ouch!
    Different contacts control the amplifiers, stylus heat, carriage brake, and cutter lift. It's really nice when that all works correctly.

    The short between the heater and +24v happened during an attempted repair. When Adam started blowing fuses, we decided he should ship it here.

    Wow, what a mess.

    So what you do is grab each contact with smooth tweezers and massage the wrinkles out of them.

    People mistakenly bend the contact arms when trying to adjust the relay. Any adjustments should only take place at the springs between the contacts.

    The carriage spindle brake +v supply contact was about 20 ohms. I had to solder the back of the contact where it was swaged into the leaf blade. That fixed it.

    It took about 4 hours of surgery to straighten it all out.

    Fair and square. Back in the box it goes.

    I went through my file cabinet and shredded a bunch of old receipts, instructions, and warranty notices for old furniture and appliances that we haven't owned in years.

    And while I was at it, went through old medical records to try to find out how much I weighed when I got married. The subject came up recently ... don't ask...
