Fly Rod Guide Wraps and Cracked Epoxy
 

During our last
Dallas Fly Fishers club outing,
I did a casual visual survey of the
condition of guide wraps.

In the bright sun it was easy and obvious to see the
occasional shimmer of cracked and de-laminating
clear epoxy. (go out side and try it !)

Is a thick glob of epoxy really the way to go?
Slick and fat and shinny? Yes
Looks good new? You bet?
Does brittle epoxy flex with the rod? Well you figure it out...

Anyway, are some epoxies better than others?
Is there a more flexible Epoxy?


What are problems with Clear Polyurethane?
Does is delaminte too easily?


Any suggestions for incredible
web sites on this subject?
(the internest is awesome!)




Thanks!

In answer to the cracking prolem: Sure you aren't using too much hardener?
The hardness (modulus ) usually increses with the amount of hardener. For the
engineers: Modulus is portional to cure agent to polymer ratio.

Yeah, then post your findings back here. I've noticed that the epoxy around
my snake guides on my 2pc 6/7 wt has cracked, and I'm worried that water
(especially the ocassional salt water) will get under the expoxy and rot out
the guides.

Epoxy isn't like polyester resin. If you use the wrong poportions, you
don't get a proper cure. Hardness is a function of the manufacturer's
formulation, not an adjustment in the mixture. Rod finishing epoxy,
like Flex-Coat is formulated to flex, and does a pretty good job of it
unless you build it up too thick. Something like 15 minute epoxy is
usually too brittle to flex when you want it too.

I know one rod builder who says you should thin the mixed flex coat
with a couple drops of MEK (Methyl-Ethyl-Keytone sp?) so you can make
a thinner coat. He usually uses 2 coats. I settle for un-thinned
flex-coat and try to put just the right amount on so I get away with
one coat.
