This is a fun fuse to build! I needed to start it upside down so the tops of the formers kept it flat on the bench. After the first 5 formers were glued, i flipped the fuse over and glued it back to the jig to keep the fire wall centered and had to prop it up level with some scrap stanchions. Then i installed the rest of the formers. At the last former i made another scrap jig to hold the aft end centered over the plan.
