Lathe Cross Slide Problem

Measure with a micrometer or height gage the overall height of the cross slide top. Subtract, you got the thickness. You need that anyhow to get the right length of engagement on mounting screws.

Add thickness found to the .926" existing thread center line. Now you have the starting "?2" dimension.

Now measure the depth from top of cross slide to existing lead screw (top of it), add 1/2 the screw's diameter and you have "?1" dimension.

What is the difference between the two center line lengths? Mill down or shim up as required.

Thank you so much Ken. I'll have to read that a few times to fully absorb it but I think I've got the gist of it. Oh, and I do have a depth micrometer that will span the dovetails so I'm good to go.
