Thanks.
Actually cutting the trees is fairly easy. Outside of the sap being like Elmers glue (around the bark/wood interface), the fresh living wood cuts only a little harder than something like Ash. I have been cutting up some year old limbs from some trees we had to remove when we built the pond. They are partially dried out but still cut fairly easily and a sharp chain will last about as long as on any other wood. It is just when the wood ages it gets like iron. Seems like the older it gets the harder it gets. If a person was going to make lumber from a big tree I would guess the best bet would be cut the timbers and let them dry for a month so the nasty sap would not foul the lumber mill. But you would definitely want to turn it into lumber before it aged over a year or so.
