I find the most effective tool for finding embedded metals to be a freshly sharpened combination blade..... unfortunately

Appreciate the comments from one and all and the link to the older site. Looks like a trip to HF is in order.

Bought this dectector from Amazon 2 years ago and it works very well. Definitely shaved my planer blades a few times.

Truth. I got some 2x4s from HomeDespot and was cutting them on my 10" SCMS. About half way through my cuts started coming out terrible - really ragged. I stopped and looked at the blade. It had a twisted tooth sticking about 1/4" to one side. Went back through the cutoffs and sure enough there was a screw I'd sliced through and didn't even notice. This was with brand new, just purchased 2x4s. Fortunately, the blade was an older one that I expected to replace at some point but it is still disheartening to have to trash a blade because of someone else's negligence.

This is why I always carefully inspect any wood I'm cutting. And, why I don't bother with recycled wood. Losing a blade sure cancels out any savings. Getting injured, even more so.

To find nails you need a metal detector of some sort and not a magnet or a stud finder. A magnet won't find them unless maybe you are holding the board upside down and the nail is just below the surface. A stud detector is too small to do any good. A metal detector is meant to find any kind of metal. A problem that you will run into is that the nail is below the surface and no way to get it out. For me, I drive the nail deeper so that the planer doesn't hit it. As far as sawing the lumber, a table saw will go right through a small nail without any noticeable damage to a blade. A bandsaw blade on the other hand will be ruined.

If I recall, the one I bought was a Garrett from a reputable supplier.

Left the battery in for too long and the contacts corroded away......

I tried my Zircon stud finder on it`s metal scan setting to see what it would do. It couldn`t fully detect a 1.5 inch finishing nail through five eighths plywood. Some of the lights lit up but not all. It had no trouble when I laid the nail on the surface so I think it would be good with a nail that was just under the surface.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
