Nice, Bubby...pretty bows, great tiller.
I think red oak gets a bad rap, too. It seems it varies a lot in quality and density, for one thing. I bought a flatsawn 4/4 nom. board once that had TWO growth rings end to end, one of which was 1/2" thick by itself. That stuff was AMAZING for oak. Then you pic up a quartersawn board with a ba-zilllion thin rings and a terrible thickness ratio, and it's like you are holding a piece of redwood.
I spend a lot off time on other sites trying to help young, first time guys get through Sam Harper's website and get their first board bow done. Most of the failures seem to come from simply not starting with the RIGHT board, or not understanding how to build up and then narrow a handle (since most of them are after a pyramid or American flatbow after reading Sam's site.) I send a lot of guys to George's site, too.
