Typically, when sawing a customer's logs on a bandmill, the damaged blade charge is around 20 bucks, and that is made clear in the beginning. People always swear up and down that there is no metal in their logs- " I been here 20 years, and never put one nail in it " Yes, but the tree has been there 60 years.
I've got a Garret scanner, like they use in the airports, and it does pretty good- I've found nails as deep as 6" under the bark. Southpa, you could probably borrow or rent a metal detector and check your log yourself. 10" is small enough that most any unit will find metal in it, if it is in there.
Jehle, I do make house calls, but not very far, like 60 miles max. Where are you located? Maybe I could put you in touch with someone local. There's mobile sawyers all over the place, but most don't advertise. Once you get started, word gets around, and you usually don't have to.
