They only go in one way so they aren't turned over. I wish it was that
simple.

Gary, are you sure the jibs aren't turned over? The "only a thin strip
comes in contact with the opposing dovetail instead of staying parallel
to the opposing dovetail" comment may indicate the jibs are in
upside-down.

Hi. I have one of those Chinese mini-mills. I know it has its
shortcomings but I just tinker around in my garage so it is OK for me.
However, the gibs seem hard to adjust... but since I don't have a real
machine to compare it to, I don't know how bad it is. I would
potentially like to improve the gibs and adjustment screws if possible.
Could some one send a picture or describe how the gibs adjusters work on
a nice quality machine?

The Chinese mini-mill has gib strips with small dimples in them. The gib
adjustment set screws are pilot dog set screws that ride in those
dimples. Pretty simple. Unfortunately, for some reason, the gibs tend to
tilt and and having the entire gib strip act as a wear area. I hope that
makes sense and I look forward to hearing how the good machines do this.

Thanks,
Gary
