a (sort of) humorous side note to this, years ago we had a family move in across the street from us, the gentleman (in the broadest sense of the term) came over one day and asked to borrow my chainsaw to cut some railroad ties he was doing some landscaping with.
I don't think I would use my chain saw to cut railroad ties with my saw, let alone loan it to someone else.
I look at it like this, I borrow something and it breaks then I will either pay to fix it or buy a new one that is as close to the original as possible. Some folks don't look at it the same way.
Best of luck and let us know how it works out.
