I tried a hand planer at first and it chewed up the floor really bad. A power planer has a rotating drum. If you need to remove more floor than a coarse sandpaper can take away, a power planer is very fast, very good. I tried a belt sander, a regular one with coarse paper. The floor was just no one close enough to smooth for that to even be useful.

On a horizontal milling machine the angle of the cutter to the milling table is fixed. It is possible to use horizontal cutters another so other angles can be made from them. One way of doing this is to fit the horizontal arbor into the vertical socket when it is in the horizontal position. Usually this might be done with this arbor horizontal.
