I do a lot of work with Doug fir because it’s cheap, even though it doesn’t machine very well. That piece of plywood is over 40 years old and began life as a shelf in a cabinet in a school built in the 70s. The straight-grained legs are from a 2x6 I got from the Home Depot’s cull pile. There’s room for improvement, but I just kind of slapped it together.
The book stand is cool because I designed it on paper using the Pythagorean theorem and the inverse tangent function. And the profile is almost spot on.
