Sidewinder

[Yardbird47@aol.com]

I recently changed casters on a 20yearold Yam P202 at a high school, and had
to check out the complaints of people who push it around. What I found was
solid sockets and stems, and properly swiveling casters. If however, you
pushed from one end, the piano wanted to move off at a 5degree angle, while
keeping its back parallel to its original orientation. (Just think of a
hammer which needs traveling but yet which stands perfectly plumb, and
imagine Scot Jones describing it to you.)

I'm embarassed not to know: is this a function of the distribution of weight
between the back casters and the toe blockcasters? The sidewinding appears to
be solely a function of where on the end you do your pushing. The piano loses
its sideways vector when you push from the corner of the keybed above the toe
block.
