Bryan,

I had the same issue.  I removed the elevator, then cut a hole In the side
of the elevator horn nearest the fuselage.  It was asizeable hole, so that I
could identify where the existing counterbalance weights stopped.  I used
the same lead strips from Lancair, cut them into short lengths, and inserted
them into the horn so that they were in contact with the existing weights.
A generous amount of flox was used to secure the weights; make sure that
tthye are really secure for safety. The hole was filed by floxing in a piece
of honeycomb.  Finally I filled it in, sanded and painted it.  It worked out
well, but you do end up with a heavy elevator.

I would not recommend relying on the other elevator making up the difference
if it is that much.  Over time you could get wear, with a slight risk of
flutter.
