    If you use a regular T shaped chuck key make the end of one arm fit the socket. While you're at it make the other end fit your cross-slide lock. If you can't find the chuck key you're stuffed anyway.

    How about a short travel festo pneumatic cylinder with the rod in the hole onto the gib, ok it would take air but if your usin it a lot might be easier than screwing in and out all the time to have an on of valve or switch, just a random thought

Regardless of what it takes to make it work itís a good mod to have toolless. I use mine on all parting and final facing ops.
    I do the same thing on my 13" Jet. The wrench also fits the compound angle clamp bolts. I modified the wrench by cutting off the out-board head and adding a 1" ball in it's place. Easier on old fingers.

    That what I described. "vise handle"

    Buy a adjustable handle similar to what old mart posted, they only cost 6-7 dollars.


    I put one on the thread dial also.

    I put a pair of adjustable handles on my lathe compound (for the rotation adjustment) long ago and am very glad I did. Had to thin the sleeve slightly with the belt sander for clearance.

    I had to make the carriage lock handle quite thin on my lathe, because the bolts for the gibs on the cross slide have to pass over top of it.---Brian

    Now THAT is a good idea. I don't need to move the threading dial as often, but making it toolless would more likely assure I remember to disengage it when I am done.

    I think faced with the same setup I'd just shorten both ends of an "L" shaped allen wrench. Trim the short end so it fits down close to the carriage so it's out of the way and trim the other long horizontal end so it's long enough to lock the carriage but not so long that it's in the way. It would live out most of the days resting right in the screw and only be removed if it happened to be in the way for some odd reason.

    I think I'd drill and tap for two locking screws to reach in and press against the tapered gib strip. The size being such that the screws are the same hex size as the carriage lock. That same trimmed hex wrench would serve all your locking needs.

    Next up from that would be to turn a locking screw with a stub sticking up then mill a standard size hex on it. Like 7/16. I'd then cut off the open end of a 7/16 combination wrench and round the end smooth so I only used the 12pt closed end. The 12 pt providing more positions and enabling faster use.

    I'd drill and tap the cross slide for 1/4-28 and fit some higher grade bolts to provide the cross slide locking feature too. Two bolts so it covers the whole range of motion or simply gives double the locking for the same moderate torque on both.

    And if the hex on the carriage lock that sticks upward is a bit longer and rounded on the end it provide a nice spot for the trimmed down closed end wrench to live when not needed without much fear of falling off into the chip tray.
