If the lever were part of the post, and not a wrench that must have "therbligs" expended on it to "find, orient, grasp, transport, align and force" in order to release the first tool, and then again to reverse the process to install the new one, it would be better, and have the "Q" portion of "QCTP" covered as well.



    Not seeing it.
    .
    By Q? I meant I was asking a QUESTION.
    Not questioning if the toolpost was QUICK ? ! ? ! ? ! ? ! ? ! ? ! ? ! ? !
    And WTF are "therbligs" ? ? ? ? ?
    Is this some British word you are trying to use that I have never heard of ?
    Are you trying to work it a treat?
    Are you trying to buy a piece of kit, even though it was only sold as one piece?
    Are you posting high ? ? ?

        but Q? Does anyone know what
        a Hardinge HLV quick change tool
        post looks like? They have a side
        and a front dovetail and the locking
        elements is in the corner, and will
        lock a toolholder in either position.
        It is a tee nut of sorts, tightened
        by a draw screw, diagonally through
        the body of the tool post. Much like
        the pictured above, but diagonally.
        It is super simple, with just 2 moving
        parts basically. It is just a bit smaller
        than the AXA size. I wonder why
        no one copies the Hardinge tool
        post design? Some copyright issue?
        Surely it has expired years ago.
        I am half tempted to measure it up
        and draw it in Solidworks and post
        it here, if there is no legal issue
        to do so. What do you all think ? ? ?

        I have modeled it up in cad and have drawings for it. I have made several of them and I like how they preform.

          No, better you wake up before posting......😁

          A "therblig" (sort of "Gilbreth" backwards) is a unit of time and motion study. A basic operation, like grasping the tool, or moving your hand to where it is. More of them in a task means slower work.

          Point was that the SCTP (slow change tool post) was not a "QCTP", because you had to go find the wrench (not part of the post), bring it over and get it into the socket head screw, loosen up the screw, THEN finally remove the holder. And do all of that again in reverse to attach the next one. So it was OK on the "CTP" part of the name, and not too swift on the "Q" part. As BCR says, it may not even be very good on repeatable location of the holder. Not much to like in the exact design shown.

          "trying to buy a piece of kit"? WTF? Mr Carson has been dead a long time, I don't need any pieces of him. Still less all of him.😏

          Oh , wait, that IS a British word that YOU are trying to use........so's the other one 😁 Stick to trying to find "a bi' o' all right".

            I usually save the beer drinking for the weekend,
            now I might consider revising my rule.
