Fuselage in process ready for planking (above left). The sides are the core of its strength. Maple motor mount for the Brison 3.2 is screwed and

radiator, epoxy them in place. Cut the screw mount from ¼-inch plywood and tap it for 10–32 threads. Reinstall the wing. Insert 2-inch 10–32 socket head nylon
bolts into the supports and screw the mounts to them. Locate the radiator as shown on the plans. Clear the sides of the radiator where the wing bolts and their sup- ports interfere. Mark the location of the ra- diator with dotted pencil marks. Cut the screws to length and epoxy the mounts in position. When cured, remove the radiator and cov-
er the marked position with wax paper. Ap- ply a mixture of resin and micro-balloons to the contacting surfaces of the radiator. Screw the radiator in place until the mix- ture cures. At that time remove the radiator and sand off the excess mixture. Cut C1 and C2 from ¼-inch lite ply. Epoxy
them in place and bridge them with a piece of ¹⁄₈׳⁄₈-inch spruce. Cut the headrest from a balsa block and carve and sand it to shape. Glue it behind C2 and fair it into the fuse- lage with a mixture of Z-Poxy and micro-bal- loons. Cut the front windshield pattern as shown on the plans and a rectangular one that fits between C1 and C2 from ¹⁄₆₄-inch plywood. Attach them to C1 and C2 with double-sided tape. Cut another set of wind- shields from .030 K&S plastic. Put on a set of woolen gloves. Place one of

the windshields on a soup plate and put it in an oven heated to 200 degrees. When you see the plastic sag, remove it and quickly mold it in place over the plywood. Trim both pieces to fit. Scuff all contacting surfaces with 100-grit sandpaper. Temporarily at- tach the windshields with Du-Bro # 2 button head sheet metal screws ³⁄₈-inch long. Re- move the screws and detail the cockpit. Per- manently attach the windshields with epoxy, some narrow tape around the fuse- lage and the screws. Cut the cowl fixture from a piece of ½-inch plywood. Any grade will do. Cut the foam mold to its side and top profile from a piece of polyethylene foam. Glue it to the fixture and sand it to shape. Apply four layers of four-ounce cloth over the foam with poly- ester finishing resin. Apply them, one im- mediately after the other. When cured, cut the cowl away from the plywood with a Dremel cut-off wheel using the plywood as a
