What's on the wheel now? Does that have to come off first? If you remove what's on the wheel, then you would have flanges on the two ends that the leather would need to be proud of, so it might not be 8 to 9 oz, but 10 to 11 oz. I would put that on with barge cement with a minimum of a 3/4 " scarf. Laid with the lap in the correct direction.
Sorry had that wrong thought
