Hi, a friend of mine asked me if i could rip him some wood boards from what looked like a 8x6x50in (approx) post, the post was extremely heavy alot heavier than your average post from a timber yard it took 2 of us to lift it into the car he was given it and was told it was probably used to hold back earth kind of what people use old railway sleepers for. The wood was a dark brown in colour with bandsaw marks on the outside and numerous splts/cracks around its outer edge when i had removed the 1st board i was surprised to find a very pretty deep red grain pattern but as to what species it is i am stumped. 2 people have said its a man made product/post which i disagree with. One thing it does have is a smell like vinegar or i personally think it smells like feet. I would appreciate any help or advice anyone can offer. Regards, Derek.
