    Default Shoving The Apron

    I remember as a late teen working on my Dad's '46-9A lathe that I would sometimes
    shove the entire saddle back out of the way as opposed to using the handwheel gear (4' bed).
    Of course, I don't do that now. I guess I must have been in a hurry at the time.

    But I was just wondering if this is bad for the saddle/apron assembly or not.
    I'm not talking "strip gear" speed, just a moderate shove. I can't see how it
    could be.

    Probably a dumb question.

    <EDIT>

    If you're strong enough, you should be able to overcome the mechanical advantage that the crank gives you. I don't see it doing any harm.

    I did it to my Dad's 9" SBA when I was a kid. I'd have to really lean into it with the lathes I have now, so much so that there'd be no point.

    You're giving me "dial envy". I bet the psychologist is gonna have a ball with that one...

    I doubt shoving it would hurt, but I always try to avoid "forcing" things.

    If you are pulling it by hand you or anyone else isn't going to break anything.

    I've done it before. The only harm would be if it slid into your tail-stock and tool bits collided or it kept sliding and pushed something off the end of the bed. Especially on bigger lathes with good ways, the carriage and tail-stock have some mass and can keep sliding if you're not careful.

    On that note, one helpful bit to do is keep a C-clamp on the right side of the bed between the ways to keep from accidentally sliding the tail-stock off the bed. We had an old Taiwan lathe with an ugly welded together tail-stock hand wheel as a reminder not to push it too far. Later we started threading 3-4" long bolts into the end of our lathe beds as stops.
