Here is my dad putting the sides on his boat. This method could be done with balsa as well if someone has an issue with CA. The clips he uses can be purchased at any office supply store.
His boat is going to have ply sides and a cedar strip planked bottom. I made him a set of frames with 1/16 cut on the sides and 1/8 cut on the bottom for this application.
Using 1/16 inch plywood for sides
I use Titebond glue instead of CA. I first clamp a 4" by 48"
piece of the plywood against the framework on the building board. I then trace around the profile of the side to outline the approximate size and shape of the plank. Using a knife, I cut around the outline to remove excess plywood leaving about a half inch extra. This should be sufficient to allow the clamps to grab the stringers along the rail and the chine. I then apply Titebond on the stringers and clamp the plywood
in place starting in the middle and working to the ends. I used about 40 clamps to ensure a tight seal (2679).
I trim the plywood back to about a 1/16 of an inch above the balsa stringer using a Stanley modeling plane (2681). These cost about $10 at Ace Hardware or any home warehouse. This takes about 5 minutes and then I use sandpaper to finish the trimming.
