I decided I wanted to make a telecaster. My first plan was to build a body blank by gluing up a bunch of pine planks we have around the house. I had it all figured out, but when I explained my plan to my wife, she quickly proved it would never work because I'd have to plane the boards down too much, so if I wanted the right depth I'd have to glue them three deep and three across and if you figure out the math and divide the cosine by the tangent of the hypotenuse we totally don't have enough wood.
Then she said "Why don't you use those big thick boards we got from your mom?"
