    No need to do that.
    There are two ways to fix that if you know how to work sheet metal without putting a kink in the metal.
    You can bend/stretch one or both of the legs or you can bend the pointer, at the base, to correct it.
    I have done both of these methods on these types of calipers for small errors.
    For larger errors you can heat the metal up before bending.
    If the caliper is plated, then heating it up is not a good option.

    Me neither

    It's hard to tell whether the copy is even steel. Could be nickel silver (unlikely).

    Very unlikely shop-made would be plated.

    I wonder if you could heat and bend the pointer without distorting the tapped hole ? (ouch)

    I like my 14K gold and diamond micrometer better than anything Stevens made, even the cute little .22 bicycle gun in the walnut case I got in 1956 or so.

    But I bet the Stevens watch charm would be worth more than my gold mike.

    Have you bagged many BICYCLES with it ?



    No no no - not the riders. They're ok. Or would be without those darned two-wheeled menaces they mount.

    Back in the day I travelled many miles on a Campagnolo-Equipped Bianchi. Sweet.

    The clueless clowns opening car doors kept me on edge, but worse were the Bicycle riders who insisted on riding AGAINST the Traffic.

    After losing a few teeth I finally put the Bianchi into very long term storage.

    I've adjusted framing squares with a hammer. I never heard it was a factory technique, but a way to correct one that was dropped or damaged. Working on the flat of the square not the edge, hammer near the inside of the corner to open up the angle and near the outside to close it up.

    One could use the same principle to correct the EBay calipers, a few taps towards the outside edge of the leg would bring the points closer together.

    Nothing mysterious about that or saw blades. It's the black art of finesse with a hammer that seems to have vanished. 😁

    I'll buy your explanation.

    Just promise not to try to explain SCRAPING to me

    Technically, these are also Calipers...

    Oh!!! I feel your pain!!! All I have are twinges of regret for not buying a mint Norris-style Plane by Footprint for $125 and the same day a complete boxed Stanley 55 for $125. Footprint ran off a few reproduction Norris planes circa 1980. This was one of those, not an original Norris but certainly a bargain at $125 none the less. I have no excuse: I had $600 of "spending money" in my pocket that day.

    OMG! You're saying dipshits with goofy haircuts and goofier attire throwing cups of paint aren't demonstrating planning and skill?

    They are demonstrating extreme salesmanship.

    I are a blacksmith, I like hammers. Scraping is a whole different kind of finesse. 😁

    For the very small amount that this caliper was off by, heating would not be needed.
    It could be done cold with no danger to distorting the tapped hole.

    It is true to a point.

    Circular saws were tensioned with saw makers hammers(Dog Head Hammers).
    Hand saws were straightened with Dog Head Hammers and Cross Face Hammers
    Many of the saw makers, such as Disston, show how to do this in their books.
    I use to have all of the saw makers hammers and straight edges and a Disston saw makes anvil.

    I took the tour of Lie Nielsen in 2017, and I saw no Hammers nor Anvils in the room they make Hand Saws at all.

    But mebe I should have looked closer.

    I do recall asking the Tour Guide, but he seemed to not know much about Saws.

    You must remember that this is the old way of manufacturing.
    Pictures of various saw makers anvils(the one marked Disston is the one I had and sold) and dog head hammer.

    There are many hammer flattening videos on Youtube. None of any great quality.

    The link to this video was posted in another thread not so long ago showing hand saws being made.
    I think they are roll tensioning the hand saws there
    HD Stock Video Footage - Workers stamp and punch the steel sheets at Henry Disston & Sons factory in Philadelphia, Pennsylvania.
    Thee is more about hammering and tensioning saws in this book if you scroll through it.
    The Hanchett saw and knife fitting manual, - Full View | HathiTrust Digital Library | HathiTrust Digital Library
    I don’t recall that there is much about hand saws in it but there is a lot about circular and band saws and some of them are as wide or wider than a hand saw.
    Regards,
    Jim

    From the 1889 J. Stevens' Arms & Tool Catalog No.8 :



    Please post pics of these Helical Coil Calipers.

    Especially if they remain GOLD PLATED !

    Note the tiny FOBs were Expensive.

    I'm guessing that mic on the end of the pin doesn't work? Would be very impressed if a miniature actually worked and the reason I became a fan of Rivett's work. It seems that everything that I have seen of Rivett's fine, incredible tools, actually work. (A tiny plane that shaves wood... that is really fun, I loved seeing this in the Tedx Talk.)

    I wonder if I have the Spring Dividers in the photo of post #58... I don't remember my pair marked by J. Stevens on the legs of the dividers; I will have to look at them tomorrow or Saturday, but they sure seem like the same shape as pictured above.
