    Default WTB K&T Model H dividing head

    WTB K&T Model H dividing head. Preference given to DH's with tailstock, plates and other accessories. Located in 99301 Pasco, WA, probably gonna have to ship. 19yo looking for a DH to do repair work and some helical gear milling, I have the mill just need a dividing head. Rusty, dusty, grimy and dirty are perfectly acceptable, but I won't pay as much when compared to a nice one. Thank you for looking

    No helical milling without the gear train driving the DH from the table screw.

    Model H came in two sizes like so

    I would certainly help this young guy out, I see his adds about, he is going after it.
    The brochure has some interesting information, such as the common acceptable tolerance of one minute of arc, problem with plain bearing dividing heads, and K&T mounting the dividing head on the right side of the table.

    Price/can you ship/any accessories? I'd call but I'm sick as a dog and my voice is nearly gone. I'll call in a few days when I'm better if you'd prefer

    I think I'm going to make the banjo for the lead attachment. Unless I can find one for an absolute steal, I can't really justify putting the money into it. The dividing head, however... I can justify the dividing head. I may just make the gears, or modify common lathe change gears to suit. Would make for a good learning experience

    I made a banjo for my 2hl universal and adapted some gears to drive my model H dividing head...I made the banjo with my K&T tool and die mill and used the banjo and gears until I found a once in a lifetime almost complete in the crate low lead attachment with all the gear sets......Bear in mind that if you decide to get a model K, it takes a foot stock peculiar to the model K unit... I think the ten and twelve inch "k" have the same offset from center line but the fourteen inch "k" has more of an offset....

    I may just make the gears
    Cincinnati lists 2800 differing four gear trains in their Table of Leads. That is quite a pile of gears

    If I end up spiral milling, I'll only make the gears I need for the spirals I'm making, and I don't think the K&T heads needed all that many gears. Lathe change gears are still an option for me, too

    Sadly it isn't comparable, K&T dividing heads were special made and had a different design. That and they can be driven to make helical/spiral gears. No idea on the make on that dividing head

    That looks like a Brown & Sharpe trunion style, or copy thereof. It doesn't appear to be set up as a universal, i.e. no place for external drive.

    B&S Trunnion style in the same upright attitude.

    Plain to see its "drive" is installed and pointing at us

    Shot from B&S's Practical Treatise on Milling and Milling Machines

    I think in the photos above that you can see some of the small bevel gear that the "drive" engages with - when it is installed

    Ok, the B&S shown has an incomplete external drive. There is a housing with a shaft and gear missing, as well as a cover.

    Just a note: Even with a full set of low lead gears for the Kearney and Trecker dividing head, one cannot get the EXACT lead needed.. In my experience, the lead needed falls in between two options so if you plan on making your gears, keep this in mind..Happy New Year.. Ramsay 1

    Here's a K&T H here in Maine.
    If it's who I think it is he's a member on PM.
    He also states pick-up only but it may be worth a try.
