For the last few years, we had some of those plastic $20 Adirondack chairs in the garden. Well, the sun got to them, and the plastic became brittle.. (my story, and I'm sticking to it!)
Now I want to build some replacements, and I need to sound out an idea; for the parts of the chairs that are duplicated, like the side rails and arms, I plan to use some seasoned redwood 2x4's I have, by profiling the 2x4 (as usual, more 1/5" x 3.5") in one piece, and then ripping down the middle to make two identical pieces.
Will this work? Will 3/4" be thick enough for the side rails and arms of the chair anyway?
