Another Nail

Tried a stud finder yet? ;-]

I use one a lot and have found nails, barb wire and lead shot before cutting the wood..

Nah. I have 3 metal detectors and 3 stud finders but haven't had much luck finding deep nails. I sawed into one with the chain saw last batch, and it was 4 inches into the log. Stupid metal detector didn't give a cheep and I could see the nail down in the cut. I just re-sharpen and carry on.

Now you know why sawyers dont' use the first 8 to 1- feet of a residential tree, or a tree in the yard of a house - unless they have a good metal detector.

I would certainly agree to that. Especially if I had an expensive band mill blade at risk.

I had occasion some years ago, to take a tour of a local sawmill near Grand Marais, innesota. They had a collection of "trophies" hanging on a wall ... metal objects they had found with their blades, and some segments of damaged blade. Pretty spectacular display. They do have a complete setup for splicing and welding and reshaping teeth on their blades. No grinding of teeth, but rather a hydraulic gizmo that clamps the blade and applies a wedging ram of some kind that re-shapes each tooth, the metal actually flowing to the desired shape. Very slick setup. Horseshoes embedded deeply in a tree were the worst. Next, ginormous spikes. An occasional rock, and then nails or staples were the most common. tom koehler

I've located barb wire when not expecting it - and my chainsaw identified a mining grade/size 3/8" square and 8" long!

The sap had eaten a lot of it up - and it was harsh itself.

Being electronics minded as well - I have always thought of a grid dip meter on a home made metal detector. But a variable frequency tone might be more pleasing.
