Forgot to say:
before fuming I have applicated several coats of 'osage soup', which caused an immediately aging process of the wood. The first pics from the building process show what happened to the yeller wood after the treatment with the soup. The yeller piece laying beside is cut off 30 min before, both came from the same stave. This is a quick method for aging osage. I will report in an extra thread.
what is osage soup?? and what's the meaning of aging? it makes wood better?
