I previously cut the forming bracket for the rear bracket and marked it for center and the distance the bracket vertically. It is used to create the form for 2 layers of BDM to create a shelf for attachment of the shearweb. Don't forget to use mold release on the angle. I wettted out 2 layers of 6.5 inch BDM material and stacked them. I folded them in half and made the fiberglass angle using the bracket I placed on the bulkhead.
