I started to fix it. First thing to do is repair some of the cracks in the larger nose piece so that it is all in the correct place/plane to graft the big broken part back on later. As you can see in the pictures the cracks are ground out so that only intact parent material is left. This is important. Get rid of all the frayed and broken material so that the new fiberglass patch has solid fiberglass to bond to.
I use a slurry of resin, chopped fiber, and micro balloons, the consistence of peanut butter to fill the crack and low spots, and then fiberglass matt to cover the slurry three or four courses thick on the back side.
The crack is positioned with a few angles across the crack. They are screwed onto the piece with sheet metal screws and then the points are ground off the back side to make it smooth with a cutoff wheel. I cover the crack first with a piece of painter tape to keep the slurry in the crack.
More pics as this progresses.
