Polish fiber optic at home? Eric R Snow 07-19-07

Greetings All,
I have a couple old Bausch & Lomb fiber optic bore scopes. The lenses
they came with are good but the polished ends of fibers have some sort
of corrosion that greatly reduces the light transmission. The steel
ferrules at the ends rusted a bit so maybe it's rust on the fiber
ends. Whatever it is it does not come off easily so I think I need to
try some sort of abrasive. Is there a household product that might
work? Like Bon-Ami? I don't want to ruin the scopes. One is cleaner
than the other and the light transmission is much better so I know
it's not the fibers themselves attenuating the light so much.
Thanks,
Eric R snow

You can get lapping film for cheap from Fiber Instrument Sales. Just
add water and keep the end perpendicular to the film and go in figure
8's. Start with the course grit and work to the fine adding water as
needed.
