Trying to fit F-421 (forward top skin). I'm having a hard time figuring out whether to cut rear edge of F-421 in a shallow circle to make it fit to the 7 degree slant (1" over 7 7/8") per dwg 26.
Per dwg 41 it looks like the slant is only 2 - 3 degrees (3/8" over 7 7/8").
Per dwg 27 it looks like top of F-421 is at 90 degree to rear side of F-421 and F-421 rear edge does not need to be cut.
If I do cut F-421 then the F-421A strip won't lay quite flat and I'll have to cut forward canopy skin to match the cut F-421.
If I don't cut then I'll have to let forward tip of canopy and its fairing overlap F-421 (extend past forward canopy skin) a bit and bend the forward square bow of canopy frame back a bit.
I hope there's still some RV-4 builders looking here.
