We do it like Gabel does: Cut the tenons first (we use a large radial arm saw), then cut the curve using a stationary band saw (we built an extra-large outfeed support to hold up the far end of the brace, as it can be heavy to hold up at the same time you're trying to steer it. Then we clean up the saw marks with a
curved-base planer . We may still use a belt sander four touch-up, depending on circumstances. Good luck, and welcome to the forum! CB.
