I have installed more than 50 sets of dollies on uprights, all the larger variety. Larger wheels deal better with thresholds. Most smaller sets I have seen have bent over time so that the castors no longer follow (castor, the verb) properly. Good luck with yours. Dollies MUST MUST MUST be installed as close to the sides of the piano as possible. Many piano bottom boards and toe (or pedal) rails will warp if they are not installed towards the outside. I have seen several pianos with dollies installed by a local store where the back of the keybed has been forced up enough to cause severe regulation problems. When installing the larger dollies, if there is a toe I will drill through the side of the dolly into the toe and insert a lag screw. This prevents the dolly from pushing up on the toe rail, and keeps the piano from rocking. (Ooooo, you have damaged the finish! Oh, yeah? This school piano is going to be beat on for sixty years and then be surplused for fifty bucks. I will opt for the solid feeling piano.) Drill your holes for the lag screws carefully, they are a soft metal and will break off if the hole is not big enough. Argh! Ask me how I know this!
