Has anyone sanded and refinished a floor laid on an angle?

Any tips? This one will be stained and I have to finish it.

With the big machine, work your way down the wall, where each stroke is longer than the last. Since you probably are new at this (otherwise you probably wouldn't need many tips about this) you will probably make lots of drum marks, and this will help reduce them because you are going over each stop mark with the next lower cut.

If you are refinishing an old nasty floor you can go around the perimeter before the first cut with the big machine so your edging goes easier.

Edging, every wall is a "short wall" and should be edged accordingly.
