Thanks. I'll give it a try. I was looking for a simpler way than using a carrier sheet and your idea sounds promising.
There's 2 gotchas in these repairs - the repaired section has to slide inside the next larger one without sticking and the next smaller one needs to slide inside the repaired one without sticking. If you need to do a repair try to use the thinnest possible repair material to keep something nasty from happening.

Bill,
Next time, spray a mist of 3M77 on the back of the fiberglass instead of the work. The fiberglass cuts much easier with no loose fibers and there is no over spray on your project.

That's probably a better system than what I used if you want to restore the strength of the pole to something close to the original. I have found that gluing the splits together with thin CA works for a temporary repair.
For my poles I glued the splits, sanded them down smooth and then used 1/2 oz fiberglass applied with CA to do a permanent repair. I spread the fiberglass out on my work surface, dusted the broken area of the pole with 3M77, rolled the pole in the glass, used a soft brush to brush the fiberglass smooth, soaked the whole glassed area with thin CA and used tissues to wipe off the excess. I cleaned the excess 3M77 off with lighter fluid. It seems to have worked pretty well. I had to repair three damaged areas that were probably close to a foot long each.

Found this while surfing around. The technique is to use a carbon sleeve whetted with epoxy and heatshrink tubing to compress it (like vacuum bagging). Then cut the heatshrink off, and viola.
