I have a feeling we went over this before, but it's been long enough that I don't recall much about it.
I have a no-date Campagnolo NR der upon which someone did a bit of home decoration. they thinned and drilled and cut the parallelogram arms to lighten them.
Problem is, over the years the outer arm has started to buckle in the middle, due to a stress riser right in the middle of the arm, caused by the cutout there. It's not broken yet, but I figure, anytime, and *pop* that'll be that.
Is it possible to removed the pins holding the arms in place, replace the arm, then re-insert the pins? I'm thinking a reasonably careful machinist could probably do it without much trouble?
Thanks for any insight you can provide.
