I have backed several red oak bows with bamboo, these were bows I saw people shooting at tournaments that were as badly tillered as possible with 5" of string follow. I should have kept my mouth shut but commented on the bows, I knew the bow owners. They all asked me if I could fix their bows, of course I said yes.
I used very thin bamboo; I did complete rebuilds and retillering with glued in reflex. The bows came out really nice and held a little reflex,
It was a lot of work to fix these bows, I vowed to keep my mouth shut in the future.
