I'm trying to fix some jalousie windows in my late mother's house. The
operators are no good and I managed to get them off of the frame by
breaking off the rusted bolts. But the windows won't open or close at
all, I suspect that the hinges have corrosion in the pins (all of
which seem to be aluminum). Any ideas of how to unstick all the
mechanisms? Would it help to use a blow torch on the hinges?
