OK, attaching the fins. The kit comes with a nice set of CNC cut fiberglass fin guides, and unlike some models from the Loco-Bovine I've gotten (Go Devil 38 for instance) these actually match, and the slots are correct. The only "issue" is that they are very slightly loose on the fins, so you can't just stand the whole rocket up and let friction hold everything just right. To sure these up I clamped them together and drilled 4 matched sets of holes. I used these holes to align and support the jigs using 1/4-threaded rod and a lot of wing nuts. The body tube was prepped by marking off the fin areas, sanding with 60 grit, and wiping down with hexanes, acetone and ethanol. All bonding on the fins was done with the recommended Scotch-Weld DP420 (I used black in case I decided not to do t2t). The fins were attached one at a time with the root edge spaced 3 inches from the aft end of the bt. A motor case was used to balance the whole setup.
