    Lets not forget that DICKEYBIRD did 5 washers with one setup. Some of the other methods suggested wouldn't have allowed that.
    Edit, guess I should have said two setups.

    Plus he did it with stuff on hand. And that often means being creative and making do. As an example of that sort of ingenuity the solution shines bright.

    Lots of great ideas in this thread but a lot of them would have required buying "stuff" that would need to be ordered in at more delay than was tolerable or which would cost more than the few bucks earned from the job.

    They weren't case hardened washers like I've done before; they'll cut OK with carbide. These weren't especially hard but some kind of weird alloy that made the swarf "sticky". All's swell that ends swell I always say!

    I especially like the title. Very timely reminder of the current state of affairs.

    Alway keep a few flat plates around to square up thin stuff in the 3 jaw.
    Some both holes.
    Then when making big discs you can part m part way and saw the rest. . Then you can clock off the parted surface.

    Thanks, I'm glad someone else feels the same. I recently modified what my dear sweet Mom used to say all the time and came up with a new version: "If you can't post something helpful or creative on the forum, don't post it!"

    ….more OT home shop machining stuff:

    In a search this morning for pics to attach with invoices to be sent to my neighbor’s co. I ran across some more weird parts that were made “under the gun” over the last year or so.

    This thing was some kind of sealing plug removal tool for an existing automated machine. It was a pain to make due to the offset taper & odd precise angles here & there. I had 2 weekends to cobble this thing up. Supposedly I’ll have to make 4 more with some tweaks later this year. Not looking forward to that!



    I made 2 of these switch brackets which had to be whittled out of a 2x4 chunk of aluminum. Nobody could tell me why it couldn’t be made from acetal or what kind of switch needs a bracket that he!! for stout! They now need 2 more but thank goodness they found somebody else to do them

    ...'nudder one:

    I made them a prototype air motor sliding driver from aluminum a couple years ago for them to test with & it worked fine. Eventually the roll-pins that slid in the slots wore them completely out. They asked for 4 more made from hard steel. This is one of the 4. It was made from 4140 & then mickey-mouse hardened on my patio with a couple propane torches, a homemade fire brick forge & a soup can half full of peanut oil. A file wouldn’t touch them & they’re still going strong.

    I immediately thought of a hydraulic or air controlled valve.

    Looks like you have fun projects.!
    At the end of the project, there is a profound difference between spare parts and extra parts.

    I don't know why but the specs of flat washers have gotten really ragged of late. Different ODs, IDs and
    thicknesses all in one batch. They're obviously all the cheap Chinese stuff but that still doesn't completely
    explain all the variations. SAE washers and hardened washers are generally pretty good.

    Boring original (hard) jaws is not a good idea. Soft jaws, on the other hand, are something that everyone
    should have in their bag of tricks. They have saved my bacon so many times over the years that I have lost
    count. And, for the do it yourself guys, they are something that can be made in a home shop. Even if you
    don't get them perfect if you true them up each time you use them they will always be perfect.

    Perhaps not but they are highly recommended.

    Another great save the day device. I also use clutch collets quite a bit...
