I like Bentlyj’s approach, as you can use joined short pieces or alternatively bent laminations to make the long ‘rockers’. The final construction would be a very strong torsion box, yet relatively light weight and all the shaping can be done with a bandsaw and finished with a router template. This is starting to look like a very doable project to me Abbas, although the veneer part might still be pretty challenging. It is a beautiful design, so whatever effort you put into it should be very rewarding. I’m really excited about watching you build it!
