Caster Repair

"The main problem then, is that the hole is not large enough to allow free rotation, so you have to router a larger cavity. I have tried to figure out a better method, rather than a router. I tried a power file. I was thinking on a Roto-Zip or hole saw, but haven't tried them yet."

I use a paring chisel or a curved gouge. Finishing up with a circular rasp in a drill. Less dust and it's fast. As for the casters, themselves, I prefer to use the double wheel Darnells w/cast sockets. Since most caster socket holes are under-sized, I enlarge with a 15/16" Spade bit, which gives a nice snug fit. (it is a bit "squirrely" to get started, so brace yourself.<G>) The added height is usually not a problem with most pianists. Of course that depends on the piano(s), as some were already a bit high on the pedals to begin with. It's a crap-shoot sometimes. Ya gots to think on your feet.<G> Oh, another consideration is that the piano need to be exactly vertical or, (better yet), slightly higher in the back than the front. This can be checked with a bubble level. It can be achieved with the ready-made cardboard washers. Makes for a safer piano and slightly lowers the pedals, as well.
