Oscar, what you have said is close to what I did. Seems most of the problem isn't delamination of the cloth on cloth but the oil in the timber causing separation of the timber from the first layer of cloth. If the delam is close to the hub the easier it is to fix. But if close to the tip, it's off to the manufacturer to fix. I have done 2 props, one at 150mm and the other at less than 300mm from centre, certainly in the first third where prop speeds are lower.
