RE: How can I bend this piece of balsa?
i use hot water on both sides of the balsa but don't drown the wood and then i make sure it's pliable then i lightly give it a contour to its' shape by hand and then put it on the area of the plane and put rubber bands around the area it's going to so that it keep its' shape. I have it so the rubber bands are spaced about one inch from each other, that way the balsa will take shape, also i make sure there is no twist in the rubber bands so they don't mark up the balsa.
Just make sure you use a rubber band that won't be too tight but tight enough to make sure it will take the shape you want.
I make the piece of balsa slighly larger than what is needed then wet it put rubber bands around it then let it dry.
Once it's dry and close to the shape i want it i trim it some more to where it's exact and if needed i'll do the wetting process with rubber bands one more time.
Once it's dry then use whatever glue you are used too.
