There should only one horizontal plane. apart from your plane to be. So
yes, that makes two, if we forget about the vertical plane. But of course
you could make diagonal planes as much as you like. Back to these pedal
floors, it's virtually impossible to really find the same plane (1) in the
plane (2) , so best to preassamble the whole lot on the bench, outside the
plane (2), make sure the pedals move smoothly, and then transfer it into
the plane (2) Now carefully fix the floorboards in position, chack again
for smooth movement before fixing them for good in the same plane (1) to
your plane (2). Hope it helps,
