The tree is probably fine. I just had one sawn with a Woodmizer that was right in front of a house. The tree people that took it down told me there was iron in it but we avoided it and what little streaking was there did not really affect the wood at all. Every tree is unique and with a bandsaw mill you can avoid any major expense if you happen to "total" a blade as they only run about $27 for the Woodmizer mills.If I lived near this tree I would get it in a heartbeat.The real expense is in having it safely taken down.
