Good mornin guys I have a question on a red elm stave I recieved,the stave came to me decrowned and I was told you work red elm down to about 1/8 inch sap wood ,it has about 1/2 inch sap wood on it now and appears to be in good solid shape.Working it down that far would leave me with a bend thru the handle bow which I dont particularly want.TBB 1 says leave the sap wood,any suggestions would be appreciated,Dave.
