Here is an update to my recent post on an Exel Black Feather carbon
pole repair.

I measured the ID of the broken pole section and it came out at about
0.500. I got a 5" carbon fiber ferrule (0.49" OD) from he
CarbonFiberTubeShop. They shipped fast and cheap I used epoxy TRA-BOND
2116 kit from Emerson and Cuming (about 8 grams of epoxy). I
constructed a basic jig to hold the pole parts straight and aligned
during curing. I did not sand and did not diamond saw to clean up the
broken parts, and just joined them back, fitting them as well as I
could. Took the poles for a roll yesterday, everything held well for a
1 hr long DP session. Total cost: about $1500 (shipping of ferrule,
epoxy). There was no carbon tape on the outside, I may add it later.
Will use the same technique to glue my other broken pole, but will
have to use a 1/4 OD carbon tube since the other pole broke at a
narrower section.
