Why go through all the agony suggested in these replies? Buy a Harbor
Freight 3200 diamond hole saw and cut out the rusted bolts complete
with a neat core of concrete. Then get some stainless bolts, pop them
in the holes with some slow cure filled epoxy and replace your railing
exactly where you want it. The depth of cut on the hole saw may
require some chisel work to get you to the depth you want, but i've
seen building maintenance guys do this easily on broken off toilet
bolts, floor mounted partitions and the like. You may get more depth
with a Milwaukee carbide hole saw, $15 or so. You should be able to
cut a neat hole in ten or fifteen minutes, my guess. The pros do it in
around five. Good luck.
