    threesixesinarow,

    That is sure a neat little machining center you have put together. It looks to be very versatile. What is the X-Y cross slide taken from?

    Thanks, Dick,

    I only just learned about the small metal slides you can buy now reading on a different forum-they look alright, or at least better for something like this than the plastic and aluminum ones I saw before.

    The table on my homemade slide is a lot narrower than those, though, and the whole thing’s about an inch shorter and has some things I didn’t see available in other designs. It made a big mess but the cast iron bar cut nicely and I didn’t have to worry about voids like on the base of the vertical slide.

    As for versatility, we’ll see! It’s harder for me using ordinary work holding tools at this scale, and so far it has only been really useful for a few tasks, like making cutters. Some kind of toggle clamp system and an x-axis lever feed will help a lot for the repetitive things I want to do with it-so far it has been easier setting up to do them on a lathe (with Unimat parts, too), like cross drilling and even slotting.

    New Unimat spindles to use in different machines - one plain bearing for slower speed and bigger through-spindle capacity, the other, just completed, with ball bearings for higher speed.

    Both take ER-16 collets.

    Both in use - they run a lot smoother than the original, partly just from separating the motors.
