I'm looking for some sort of small platform table 3" x 4" on a dovetail slideway with a leadscrew like the crosslide on a metal lathe. I need to have a Z axis on a small sherline 4000 lathe that I will be modifying for a special project that will sort of turn it into a horizontal mill. I need to be able to adjust the cutter height up and down over the bed. If you have the equivalent of a sherline crosslide I can make it work. It needs to be fairly precision and a micrometer dial would be great. OR if you have the same sort of machine as in this video please let me know. https://www.youtube.com/watch?v=bMD0DptdAwo thank you.
