Here is the 1/32 ply fuselage doubler ready to be offered up to the fuselage side
Here is the fuselage doubler after being tacked to the side of the fuselage. The instructions indicate that it can be first tacked in place with slow CA. I would suggest that you get it positioned quickly as even slow CA doesn't give you a lot of working time. The main purpose of the slow glue is to hold the doubler in place while you use the lightening holes as access to wick drops of thin CA between the plywood and the balsa fuselage side. The notch on the long flat side of the fuselage is for the landing gear plate. This notch is present on both the fuselage side and the doubler. It is best not to get too much glue in any of the rectangular slots as various formers and plates will be glued into them later.
