[TowerTalk] Centre Insulator - fiberglass or Garolite rod

Jim Advised:

<<I've used it <Garolite>, and many other similar products.  The problem 
with machining is that it's made of glass fibers, which are harder than 
steel, and so, cause your steel cutting tools to go dull instantly. (just 
like drilling or cutting fiberglass or glass-epoxy circuit boards) 
Interestingly, though, regular old aluminum oxide sandpaper works quite well 
(alumina being harder than glass).  Carbide works too. Coarse grit, lots of 
water to carry away the dust, chuck it up in the lathe and have at 
it...snip...>>

Hi Jim,
Thanks for the extra info. I'll bet the dust is hazardous, too!

How does Garolite stand up to UV?
