I also come from a woodworking background. I just chucked a sanding drum in my drill press and use that to sand my edges.
After sanding, I bevel my edges, wet, burnish, let the edge dry then gum trag, burnish, let it dry then gum trag and burnish again. After that dries, I do the stitchin', top coat then burnish the edge one more time.
I'm pleased with how it turned out. I do all my burnishing by hand.
