After turning the hull over and positioning it in the cradle I spent a couple hours shoving them around to get them aligned. Then I put all of the pieces together to see how it fit. I was happy, particularly with the alignment of the beams to the cabin ends as I under stand this is a problem.
One thing I was not happy with is the cabin front being lower than the main beam ends. If I’d known this at the beginning, I’d have raised the roof.
