    lathe chuck key mod

    I don't know why I hadn't done this to the chuck key on this lathe a long time ago.
    If there is one thing around a lathe that is always in the same place when you put it down, is the chuck key.
    Mine hangs in a short pipe welded to the skirt of the swarth/ coolant tray. It is always within easy reach and never misplaced, not true for say a combination wrench or an adjustable although most of mine are hanging on a wall somewhere. I've always just kept 1 laying somewhere around the lathe for changing the position of the tool post, usually cluttering up the swarth tray or on the near by parts table. Also either never within easy reach or in the way of other things.
    So why not end that problem once and for all.
    What I did was weld a Chineseium 1 1/8 socket to the chuck key at the cross. Now a tool to loosen and tighten the tool post top nut is right at hand because the socket to fit the nut will never wander off like a combi. wrench or an adjustable.Plus as an added bonus the socket makes it much easier to pick up the chuck key out of its dedicated spot.

    As you can see where the chuck key stays the addition of the socket makes it much easier to grab hold of, I think I like this part of the addition the most, even though changing the position of the tool post is now a breeze. And I change position of it almost as much as I change parts in the the chuck.

    Like many things that show genius, it's obvious once you see it. Also makes you smack your forehead that you did not!

    In the past on a chuck key for a lathe I used to have I welded a cut off 1/2" drive extension my theory or thinking was I could just change out to which ever socket size I wanted at the time. This was well and good but on that lathe there were 3 or 4 various sizes of nuts or bolts I regularly changed things on. It turned out to be a royal pain using the chuck key for everything plus there was the clutter and having to keep up with all of the sizes.
    This lathe has 3 sizes as well that I use frequently but a socket will only fit on 1 of them that being the tool post. the lock bolts for the tail stock are recessed and can only be gotten at by the wrench made for it or a combination wrench, that wrench remains on it at all times.
    For the carriage lock most of the time the compound slide is covering it so only a combination wrench will work there so I just leave a 3/4 box end on it at all times as well.
    leaving only the tool post that I had to hunt for the wrench. The socket on the chuck key solved that issue.
    Now I need to do the same thing for my other lathes.
