    The tailstock spindle on my B227L lathe from busy Bee Tools had no graduations on the spindle. This didn't hurt the operation of the lathe in any way, but it drove me a little crazy every time I had to drill a hole to a specific depth.

    So---I complained about this over on another machining forum, and someone over there gave me a great solution. First, I found a "spare" machinists scale and sawed out a strip 3/8" wide x 1.5" long. (The total travel of my spindle is only about 1 5/8").

    Then I set the tailstock spindle up in my mill, and with a 3/8" milling cutter, I milled a slot long and deep enough to accept the peice of scale I had cut off.

    A quick trial fit while things are still set up in the milling vice--

    I used some #648 Loctite to glue the scale in place, and Voila'---I now have a graduated spindle.

    Great way to fix the problem but for what it would of cost at manufacture you've got to wonder why it was left off

    Nice idea, I'm going to try and remember this for when I need it. Good use for a 6" scale, other than the coffee stirring I usually use one for. ;D

    Creative solution to a frustrating - very nice.

    However, I have the same lathe and the tailstock handwheel on mine is graduated - one revolution is .125" with markings all round. Not as slick as you "glued on" ruler however.

    Is your's not?

    Yes, mine has the dial graduations, but I'm more comfrotable with a scale I can read.---Brian

    Maybe tilted so as not to interfere with the lock handle on top?
    Works well for me and my quill is already graduated. Just much easier to read and re zero at any point.
