So after I talked to PM I forgot that we didn't resolve the matter of the wedge nuts supplied not being tapped (for what needs to be M8 X 1.25 (M8 coarse)).
M8 wedge nuts are readily available in the UK and India, but I definitely couldn't find any in the US. These are also called Vee Nuts, V-Nuts or Vee Wedge Nuts. I guess they are common over there, but not here.
Here is a picture of what one would use to mount something (e.g. a limit switch or stop of some kind) in the front dovetail slot of a PM-25MV milling machine.

If anybody knows where to get these in the US, I would be interested to know.
Looks like a good beginning milling project!
A lot of people would probably just grind down a T-nut.
Anyway, I found it odd that these were not readily available.
