    You could get an old throw-away car leaf spring and hammer/anvil forge it to be about 8" long and at fat at one end. Hammer and square punch out the square hole. and whack around to about 1/2", then resize the hole and oil quench. then heat it up and draw the hardness back to about 42-45R. then bench grind the part that needs go into the bore.
    likely it might only cost 10 bucks for an old leaf spring at the junkyard.

    F**k's sake? No need to start with Iron ore.

    Just order the stock square socket and use fire and hammer to alter the size.

    It is already decent steel in the needed shape, and the nearest stock sizes are right NEXT to the target in dimension.

    I'd still pull the existing pinions and reduce THEM to a stocked square size. It is fast and easy - there just ain't that much to remove.

    Only 62?

    So I was using TR before you were born? Mentor's company Purchasing Department had them. Another bud's Dad had Teletype service. Not to his home. He owned an AM broadcast radio station. API link. Western Union existed, already, too.

    LOTS of things worked rather well UNTIL ... Jim Rozen started doing stupid stuff.

    No fear.

    We'll put it on your tab.

    Manage to bankrupt your contrarian arse, and that could be one less brain-dead Marxist voting twice, next election.

    Long arms, Bristol Wrench have. Splined, too!

    If you have an odd size male square,
    I would try a 12 point socket.
    If you have an inch and metric set
    you will likely find one that is a
    good snug fit. I have a Skinner
    chuck that I use on my Brown and
    Sharpe #13 grinder, a true grinder
    chuck with the sealed center. Anyhow
    I use a 7/16" 8 point socket and a
    tee wrench. Fits perfect.

    To the OP - what's the desired OD of the wrench, where it fits into the chuck body?

    EIGHT POINT is righteous.

    12-point can bugger the p**s out of it. Seriously. Don't-even...

    "Somewhere.." I have several 1/32" sized 12-point and one or two in 1/64" sizes that were custom items "back in the day" some among us figured we would adopt 32nds and 64ths and NOT ever have to mess with that newfangled "Metric" BS.

    Dumb move, as it turned out.

    Metric was dead-easy if we simply bought two separate but waaaay smaller count sets of wrenches and shifted MENTAL gears to suit the wehicle.

    So we did that instead.

    Then you ran into foolishness such as the Denso A/C compressor mount on the '84 "Franco-American (Japanese)" Jeep Wagoneer four-banger.

    Barefoot-poor AMC used whatever leftovers the "Big Three" had remaindered in any given week! Might be GMC parts, Ford parts, or MOPAR!

    Between brackets and braces, 4 of 9 fasteners were metric, the other five were US! Just for the A/C compressor.

    I have the brother chuck to the OP's: a 6" Skinner 3 jaw with both a scroll and independent adjustment of each jaw. The scroll pinions have a 7/16" male square so I milled a square in the end of a piece of 3/4" round steel. Took about 45 minutes including making the handle. Piece of cake and I am not a particularly fast worker.

    The OD is 1".

    I don't look at this thread very often since farktard won't just STFU and go away.

    That's how s**t is meant to work.

    You had a stock size a person could "just buy". So you had to go and make one to fit.

    HE has an odd size not easy to "just buy". So he is compelled to buy one that DOES fit!

    Rozen-San - given the OD - will nail the OD. But make the square socket the wrong size.

    Go figure it's a damned good job we ain't runnin' the Government?

    Those things were made in most sizes. I have an assortment in various sizes in a drawer somewhere. Every time I think about getting rid of them I think again about the ones now in use around here.

    I have a 4 jaw with those knuckle-busters, and when I needed a wrench for it, I found it in the drawer. Ditto for the table clamp on the old Greenfield grinder. And a number of other things.

    Heck, I even have a dogbone ratchet with 4 sizes of square socket. Seems like they are everywhere when you do NOT need them. Which is when I bought the lot.

    If you just gotta make one, OK. Otherwise...........

    The size of that square's been established though. 15/32, right? Easy to shaper it to size.

    Heat and hammer are cheaper and faster. And I have both of a 12" shaper and a 7" slotter.. mills.. drill presses. even a panto-engraver that could "carve" at it.

    NONE OF WHICH are remotely worth the BOTHER of setting up!

    It ain't a Grob spllne.

    Only a ham-sandwich-ignorant SQUARE HOLE 1/32" off a COMMON store-bought size!

    FIX the obsolete choice OF said size .....by altering the "PROBLEM side" - the pinion ends need to be trimmed a skosh..are probably raggedy ANYWAY..

    and END of "problem" ever-after.

    "Store bought" becomes the solution.

    BFD.

    Meh. Not in a rush.
    Last time I even remotely try to assist you in any way.

    It appears OP has no intention of even attempting this little project, more so this thread was started to get the OP's
    website address splattered as many times as possible here, thereby driving "google hits" .

    Don’t know why you’re getting all worked up. It was a joke.

    I was merely looking for information. I have it now. Thank you to all that provided some assistance or ideas.

    I have no idea if I will make one, buy one, or just sell the dividing head (highly unlikely). My Bridgeport is still in pieces as I have decided to just do a full tear down and rebuild.

    But I do like to try and plan ahead.

    PS:

    That was a "joke"
