Thanks for the reply Alan. My apologies for the delayed response, I've been
absent for a week or so.
I try to keep the cross slide table central on the saddle whenever I machine
anything and I only moved it to what I consider an extreme position when I
initially found the problem.
Although, your suggestion of checking for flatness will be taken into
This being a relatively new machine though, I certainly hope that, that would
not be the case. Everything I have considered so far points to the gib and I
hope that, that is all it is.
With some luck, I should be able to attack the problem in the next day or two
and find out for sure just what it is.
As I've had little response to this problem, I'm assuming that this is not a
typical scenario with the Sherline machines.

From your description it sounds like either your gib is too fat in the
middle or you are running the cross-slide out so far that you have
reduced the dovetail contact area too much.
Perhaps it's just a defective gib though.
You should check the saddle edges and cross-slide edges for flatness.
You should check the gib for flatness - lay it down on a flat surface
and lay a straightedge on it, then see if you can slide a feeler gauge
under it anywhere.
