Now that the vent mounting plates have been trimmed, I can now work on the F-793 vent brackets. Originally I wasn't happy with my first attempt at the F-793 brackets. they were ok, but I can make them better. Since I have extra material, I quickly made 2 new ones and trimmed them up to suit the revised vent mount plates.
After painstakingly trimming the half moon shape to allow the vents to next into them, I now need to locate the two mounting holes in each located closest to the fuselage side. Well... I put my 3D printer to work again and made a drill template to locate the holes.
