I've wanted some wooden ones for a while, and came across a "hobby pack" of 1/16 3"X24" walnut slats. The cutting of the slats was easy on a bandsaw, I taped all 22 pieces together and cut and shaped them all at once. None of my saws could accurately cut the angle for the back pieces, so I cut 80 spacers at the proper thickness and angle by hand with a razor saw on a miniature mitre box I made. That took the longest, 2 nights, 3 whiskey/sodas per night. I built a jig for assembly. They are the exact dimensions, angle, and slat number as the originals, and surprisingly sturdy, due to being supported on all corners. Yeah, I know the wood doesn't match, but the flash made them look much brighter than they are.
Got about 3 after work sessions in them.
