It seems the plastic housing has deformed to slightly oval tubes or

out the 2 deeper AAs, wedged in ther, no corrossion , just lack of
freeboard. Any ideas how to enlarge the bores a bit, no engineering
reamer available. Those silly sandpaper cylinders on a rubber cylinder
"mandrel" for "Dremmels" would do the job if there was a way to extend
the shaft. I'll try the core of a "choc block" connector as a coupler,
but any other ideas?
