Do link belts stretch over time, requiring the
removal of some links periodically?

They do stretch for the first few hours of use. BTW, so do regular v-
belts, at least the good ones. After twenty to twenty-five hours of use
under load, they should be re-tensioned (and possibly have a link
removed). At hobby-duty levels it can take awhile to put 25 hours on a
machine.
