Well, I don’t think the front cabin roof will be sagging nearly as much after today.
Dane and I got out in the VERY hot afternoon sun and built two "trusses" of curved plywood with a sidepiece. The plans have a design for the correct roof curve, so we used that, jacked things up put them in place.
Put a side piece of 2×2 on each to keep them from twisting or warping… looks like it will work. The plans allow for the cabin height to be raised a little, which I did for better headroom. This makes clearance with these crosspieces no issue at all, unless you are awfully tall.
Time = 2 hours
