Part of the joy of homebuilding is the learning of new skills.
Pick a proven design and go for it. To try to mix media in order to use
what limited skills one already has just ends up in frustration, money
spent and no flyable airplane in most cases.
It helps to choose a design that's being built in your area by
a friendly homebuilder who can show you how to do some of it. It also
helps to be building an airplane for which materials are readily
available. Be aware that suitable wood is increasingly rare and
expensive and needs hangaring if it's to last any time at all. I own a
wooden airplane, and the next will be aluminum.
