But as Norman mentioned, turning the wheels to cross each others' paths also works to stop the piano from rolling, and if one doesn't wedge the dolly to the floor, that also needs to be handled. Ideally, I prefer to avoid external implements that can be lost or mis-applied, so a permanent jack-post plus either wheel brakes or clever wheel-positioning would be my first choice. I did say something way earlier about wedges under wheels, and I don't think that would be as positive a stop as the brakes or positioning. Unless somebody thinks or knows otherwise? ~Mark Schecter</div> <div> On Jan 28, 2013, at 9:04 PM, Susan Kline <<a moz-do-not-send="true" href="mailto:skline@peak.org">skline@peak.org</a>> wrote: </div> <blockquote type="cite"> <div> <meta content="text/html;charset=UTF-8" http-equiv="Content-Type"> Yeah, that's what I meant!

But I don't know for sure exactly how they did it, because by the time I got there for touchup just before doors, they had wedged the dolly and he was happy. I don't fault the player at all, because I have felt the movement and I understand it could be troubling for some players. In fact, I appreciate his input, as this solution that I will implement will benefit everybody, even though many won't know it. My thanks to you and others who have contributed to this thread, as I now have a better idea than I started with, and that is a wonderful thing.

Joe I do not have a picture of the unit installed and I am no longer on contract with the particular university where I installed this unit.Â It is still on the piano as I occasionally attend performances there. Â  Because it is painted black and made of fairly thin pipe it fades into the background fairly easily and is not a distraction.Â  The reason for designing it in the first place was to help the truck roll easily as the casters were so canted they did not swivel easily and the piano was very difficult to steer and turn.
