On elevator balancing: I do not know how Bingham balanced his, but in digging into this issue a bit I have seen two successful approaches used on KRs. The first, poached from how many F1s are done is to balance with an internal weight on an arm attached at the elevator bell crank. The second, as you suggest, is weights attached at the elevator tips.
One thing to keep in mind is that stresses on the weight attachments can be rather high. If I recall correctly Barnaby Wainfan in one of his articles said that control surface weight systems should be designed for a 40 g minimum.
