What are cateye bodies made of

I don't know; you would have to ask them. I'd expect it to be a
filled resin of some sort, but there are many candidates with varying
charcteristics.

Dear Gloucester,

If we're talking about the stuff inside that keeps the body of a
cateye nice and round, it's known as the vitreous humor:

Eye surgeons fear the escape of this vile jelly when removing a cloudy
lens in a cat(aract) operation or any other surgery. "Losing vitreous"
is worse than seeing an inflated tire start to creep off the rim at
120 psi--tubes, after all, can be replaced. So eye cutters try to keep
the stuff pushed inside, where it belongs:

"Cataract surgery was once a much more invasive and hazardous
procedure than it is today. Large incisions and intracapsular lens
extractions were not uncommonly associated with significant vitreous
bulging and even vitreous loss. The situation is well described in
the words of Dr. Paul Honan (1), whose account of the development of
the Honan balloon can be found elsewhere in this issue of OASIS.
Suffice it to say that ocular compression was born of the fear of
losing vitreous during cataract surgery with its attendant
complications resulting in visual compromise or loss. That fear
exists to this day, especially when large incisions are required, as
in corneal transplant surgery and during the occasional ECCE."

As for repairing an ordinary cyclocomputer, the easiest solution is to
stop by WalMart and get a new red $10 Schwinn cyclocomputer with a
fresh battery and a trip meter that reads in increments of 0.001
miles.

See you around,
