Thanks Hamish. Actually it was made from a half split of a four inch sapling and it dried into about three inches of reflex, all of which pulled out during tillering, leaving me with about an inch or so of set. I did flip the tips a little during the heating process, to help with the string angle some so it wouldn't pinch my big mits while drawing the string, which left the bow right at zero after shooting in. White oak without the heat tempering process is tension strong, but can be very prone to taking set - heat treating it is the key to getting the most from this species. I have had best results with toasting it right after low bracing the bow for the first time. I have a sister to this stave that I am trying to figure out what to do with...
