This is the first time I've attempted to use graphite arbors in a build, and I'd like it to be fairly right , as it's for the rod swap!! With the set up, we got a pair of ga's. I was able, with no trouble at all, to get them filed down to the proper size for the blank ... but them came the question. Do you leave them as "pairs", one at the front end of the seat, and one the back end? If so what do you do for the mid section? Leave it open? Put a few rounds of tape? I'm guessing the "divots" in the arbors are there to hold epoxy, and are not guides to cut the arbors? Think; spacing them the length of the reel seat?? Anybody on now with an answer? Surely, I'm not the only one using them for the first time, and not a clue on how to use them!!!
