Hi, Chris........AS THE ORIGINAL , can be a challenge , no ? If I were truly obstinate with the mahogany thing, this is what I would try and maybe put a piece of ash in a vice and give it a twist to fracture and then a piece of sepele, maybe even record the location and the force to cause fractures. Then, because you are intrigued, take another sepele and go to the drill press and set up for many ( ? ) , 3/8 ( ? ) dowel inserts drilled to be hidden on the outside edges . Maybe not worry about holes for caning. You need to be retired for this trial and have a strong sense of the fantastic.
Good luck and have fun, and if it works, tell no one but, maybe me and/or your wife.
