  • Added some gib screws to my Atlas 10 topslide

    I noticed that the topslide only had 3 gib screws and that there was a small range of positions where there would be only 1 screw doing all the work.


    That didn't seem right to me so I decided to add 2 screws to the mix. First I picked up the centerline of the existing holes and their spacing:


    Using a small clamp and hex key to hold the gib in place while drilling a 0.130" diameter dimple:


    2 new holes drilled and ready for tapping:


    Continued in next post.

    Modified some 10-32 x 1" cap screws by turning the tips down to 0.080":


    Here it is with the topslide cranked all the way in (still need a jam nut for the leftmost screw):


    And the topslide cranked all the way out:


    And one last shot:

        Very nice RichR. Plus I learned something. I'd never thought of holding a screw in a die with a jam nut. Sure beats two or three nuts or even a split nut, I'm thinking. Thanks.

          I shall remember this good work

            How are you holding the screw in the lathe chuck? Is it a die and nut?

              You can also use a 5C collet. Just insert the screw from the back side
              before you install the collet.

                Yah! That's a great how-to tip. No more need to make split nuts!

                  Thanks guys. I had pulled out the die to have handy in case I buggered the threads and then realized I could just hold the screw in the die.

                  before you install the collet.
                  I suppose I could have done that, if I had collets for my lathe. I had considered drilling and slitting a piece of aluminum into sort of a poor mans collet, but
                  the die was quicker and easier.
