    Default Finding nail and screws

    Who can advise of whether electronic 'stud finders' are effective in discovering old nails and screws in wood?

    No use to you if you're looking for them in 'quality' products with the possibility of their being of brass or stainless, but I use bits of magnet. One benefit is that you can leave them to mark the line of the stud instead of having to mark it some other way.

    (Dead hard drives are a good source of strong magnets).

    Stud detectors not too good at finding small metal objects. If you Google Woodworking Metal Detectors, some wand types should come up, which are far more sensitive but, read independent reviews.

    Small metal object detectors in the food and farming industry tend to be large and expensive.

    My thoughts turn to security wand detectors which, by implication, should be capable of picking up the presence of small metal objects, but with what precision and accuracy, I wot not.

    I think, therefore I am. I am, therefore I sail.

    Best thing to find old screws & hidden nails is a newly sharpened saw
    It is all down to the fact that my wife does not understand me !!

    Rare earth magnets are pretty good, pick up a nail through an inch of wood.

    My wife used to be the local organiser for Project Linus, a charity which provided quilts for sick or otherwise needy children. Before passing on donated quilts she was careful to check that pins or needles had not been accidentally left inside. I thought one of these hand-held wands would simplify the process, but even with the sensitivity set to maximum it would not pick up a pin or needle.

    You might try a surface coating meter. Used to determine the thickness of galvanising or paint on a steel substrate. They are very sensitive (at short range) - though whether they pick up a steel nail in 1" of wood I don't know.

    A plane can be quite effective too!

    I have always found a fine toothed festool blade to be quite effective ( and more expensive)
