Replacement Casters & New Tool

[Tom Dickson]

Hi, John,

Most of these casters that I have put on are in private homes.  The main 
situation is that the folks have put in hardwood and they don't want the old 
metal casters rolling over their floors.  I have put a few sets on pianos in 
rec areas of seniors' homes and several community centers.  Many of these 
were done at least 5 years ago.  So far, no complaints.

What type of moving do you think they're doing with these pianos?  If it's 
from one end of the school to the other, that can be a long haul and can 
cover a lot of different "terrain".  Perhaps the stresses of student 
maneuvering and going over sills, various types of mats, etc., take their 
toll on the casters.

But... my experience, and my impression, is that these wheels are pretty 
substantial, so I am quite surprised that they are failing!  Could this be a 
"bad batch"?

Sorry for nothing definitive!
