    I have a leedscrew reverse equiped lathe and in moving the lever up the spindle comes on but when moving the lever down, nothing until I rotate the shaft by hand the last litle bit, the lever on my right has too much slop and I would like to tighten that fit a bit, any one out there with an answer?
    thanks

    This handle controls a segment of a gear that engages another that's engaged to the slot on the leadscrew reverse shaft. The only way to fix this would be to remove the SHCS holding the lower box to the apron to lower the box, set the rod into the center position as well as the lever and reconnect things. That should reset things wto work properly.

    If it doesn't I'd bet that the problem is where the leadscrew reverse rod connects to the cam switches at the tail of the lathe. Check to see if you have a lot of slop in the connection, if so you might have to ream up to the next taper pin size and refit that connection.

    Thanks for the reply.
    I have allready tried to re-engage the "half gears" and the poor fit has not improved, I am positive the leadscrew reverse shaft fit is not it, what I would like to do is to reduce the clearence in the fit of the two half gears, any sugestions?

    A similar problem occured on my machine awhile back. The cam switches at the tailstock end of the lathe can be adjusted. I can't quite remeber how the adjustment works, but if you take off the cover of the cam-switch casting I think it is pretty easy to figure out.

    The key that rides in the slot on shaft is shot.

    Go down to the topic "Apron disasembly/
    w leadscrew reverse on this board. I talk on how to make a key for that rod. Hope it helps.
