Here's the backrest pretty much done. I'll take it apart, bead blast it and paint it. I'm going to leave it adjustable at the present time. With this setup I can adjust the backrest up and down, in and out, and tilt it forward or back. In one of the pictures of me sitting on it, you can see how it conforms to my back. I had about 2 inches of foam and I took that to the upholstry shop and had the lady sew it up for me. I weighed the backrest assembly..the wood, metal frame, and it weighs five pounds. I'll be trying this out today. It was late last night when I got it done. I believe the secret to getting one that feels good when riding is to have a lot of adjustments. After you get it all adjusted, you can get rid of the bigger adjustment arms and just spot weld some smaller brackets there.
