     I made a belt for our old Winsco N100V VDG out
of a strip of black spandex back in the previous century (Oct of
'97).  Last spring it had to be retired, it just wanted to curl in
from the edges and run off the end of the roller.  So that's 5 1/2
years, compared to ~1 yr for the replacement belts.  It requires a
little sewing skill.  If you're interested in details, let me
know...

P.S. The belt made from surgical tubing sounds interesting
(howstuffworks.com).  Surgical tubing lasts awhile.  Has
anybody tried this?

Hello
tappers,



 Does anyone have ideas about replacement
belts for the Winsco Van de Graaff generator? The belts can be purchased
from Sargent Welch for about $10. The problem is these rubber belts only
last from 3 to 6 months in our science building's (we share with
chemistry) caustic environment. Our budget (none for the moment) does not
permit us to stock up and these replacement belts go bad on the shelf as
well. Any ideas for homemade belts?



Thanks,



Brian Magness
