My question is really about modifying store-bought furniture, but is
just as applicable to a chair I might make.

I have a bar stool with turned and slightly splayed legs. The bottoms
of the legs are cut perpendicular to the axis of the leg rather than
on the plane of the floor. I'm thinking of putting it on my bench,
and using a pencil or plane iron bevel-side down to mark a uniform
distance up from the bench, then suing a block plane to trim these leg
ends to be coplanar. And reason not to do that?

The stool is on a hardwood floor finished in urethane. In the perfect
world, the floor would stay so clean that no grit would ever get
between the bottom of the stool and the floor, thus no scratches. In
the real world, I have had pretty good luck with hard felt self-stick
pads from HD, except that the adhesive doesn't hold all that great, so
I end up having to replace them periodically. The low-friction hard
plastic (UHMW?) pads don't seem to work as well in preventing
scratches from floor grit. Any other ideas? (The floor is already
down, so mag-lev is probably not feasibleg)
