I want to make a wooden stool, quite an unsophisticated one,
with four legs square in cross section.

The reason that milkmaid stools were made with three legs is that three
legs will always all touch the ground, no matter how uneven, while four
legs will only all touch if the surface is perfectly flat (assuming no
errors in making the stool).

That's true, but even a wobbly four legged stool won't fall over as easily
as a three legged stool.

It will be used for usual stooly things such as standing
on to reach things that are high up,

A very good reason for wanting one that does not wobble, although I have a
small set of aluminium steps for such jobs, which I consider to be much
safer.

I agree. We have one upstairs and one downstairs.
