I think I finally got the Cabin Top trimmed to fit. Thanks to the Kayak Hoist, I was able to take it on and off easily to fine tune the fit. I know that I'll have some filling to do once it's ready for the final install, but it's pretty good right now. The plans have me clamping the rear edge of the door frame into place and prior to match drilling. My next job is to temporarily install the top skin aft of the cabin top before match drilling. Having the Cabin Top on really makes it look like an airplane!
