    Oh and I will add, Free Hand Form Tool Grinder ..
    now when you are setting stops and moving tool lengths , that is still tool setting right ?
    it is just swimming and clamping that falls under Jiggle Jacking , correct ?

    or perhaps it should be Jiggle Jacker Savaant ....
    As long as you stay OUT of the porn industry, I think that is OK to
    include in your resume. Else you might be considered one step
    up from being a fluffer.

    So talking about this indexing toolpost thing and convenience that it offers,
    here is my Tsugami turret lathe, copy of a Hardinge HC lathe.
    I find myself using it as a general purpose lathe, pretty much for small work
    on anything that does not need a tailstock. I have it tooled up, so 90% of the
    time, I don't have to swap out any tooling. One nice thing, I can put small
    boring bars (Like Micro 100 carbide bars) in the drill chuck, because it can
    move from other than being centered. Even though I have 5 other lathes
    I just can't bring myself to sell this one, because it is so handy.

    ---Doozer

    Edit note: Notice there are two ECL dovetail toolholders with a height
    adjustment feature. These make it so nice to center the tools, instead
    of jiggle jacking around with the fixed height ones.

    The "find", is simply that your hand has to be moved (transport empty) to the location of the item, and has to be located over the item in position so it can be picked up. It makes NO difference that you know where it is, you are not "in position" to grab it until your hand is there (find). Then you grab it (acquire), and move it back (transport) to where it is to be used. The toolholder only fits one way, so it has to be "aligned" before it is put on the post, etc, etc. ...

    This so much made me laugh. Thanks Tomato.

    I would be very surprised at a home shop that does a Taylor study (time and motion)
    Had a new boss at work once who thought they were the greatest thing
    He gave up after 6 months when they finally convinced him that they had already optimized their process as much as possible for decades before he was even born. With no formal study of it at all, just common sense driven by desire for profits.

    You obviously know nothing about time and motion studies.

    Those are "elementary operations", and each is assigned a time, etc. In factory work (I know, how quaint to think that there could be such a thing as a factory) those tiny bits of work add up quickly to a lot of time and money. In the shop, it's up to the user, and few worry about it until they have to do the same operation sequence many times.

    The "find", is simply that your hand has to be moved (transport empty) to the location of the item, and has to be located over the item in position so it can be picked up. It makes NO difference that you know where it is, you are not "in position" to grab it until your hand is there (find). Then you grab it (acquire), and move it back (transport) to where it is to be used. The toolholder only fits one way, so it has to be "aligned" before it is put on the post, etc, etc.

    In the same way, you have a place the toolholders are set when not in use (on table next to workstation, perhaps), and you have to put the one you take off in a specific place so you can get it again. Makes NO difference that you know where that is.

    Turning a toolholder that snaps into position is clearly less of these "micro-operations" per tool change. That stuff adds up when doing the same thing over and over dozens of times, or potentially hundreds of times per day. It is why turret lathes were invented. For that matter, it is why the QCTP was invented.

    One machine I wished I had bought was a small Burgmaster turret drill , about a 18 in square foot print I am guessing. Benchtop, easy to move... would have been fun.

    I like turret lathes, I use two venerated brands when need be.
    A small Hardinge, what a joy this machine is, quiet and has a large spindle speed range for such an old machine.


    Also a big, ugly, smelly yet surprisingly quiet Warner & Swasey #5, this is a powerful machine. 20" chuck.
