    Default New blades in the thicknesser, found a nail already. Time to buy a metal detector

    I love playing with recycled timber, but nails, no words. Just replaced the knives, just found a nail. Thought I punched them all out. So annoying. At $80 a set I think its time to buy a metal detector.

    Suggestions?

    Yes Pearo, they are great at finding nails. Remember that rather than replacing or even sharpening the blades if the nick is not too large you can offset the blades so that the nick won't leave a ridge because the other blade will remove it.

    Jointers & thicknessers seem to be the best metal detectors around! I go over any recycled timber with a strong rare earth magnet, which seems to do a good job. Its just a small bar about 75mm long and 3mm thick.

    Pearo,

    This is the one I use.

    Thought something was wrong with it as it went 'beep' but I couldn't see the nail. The nail was just under the surface.....so it saved my blades.

    I work a lot with recycled timber so a metal detector is a MUST.

    Cheers, I had looked at them. Might go grab one this afternoon.

    @ Larry M, I normally just move the knives over a bit. Works for a while at least!

    A metal detector is good to have in the shed. Rare earth magnet also good option to narrow down into the area.

    Good Morning Pearo

    Unlike the others, I do not have a lot of faith in metal detectors on salvaged timbers. Imbedded grit, shells and marine borer excrement trails (wharf timbers) and gravel (railway sleepers) can do as much damage as nails but wil never be detected by a metal detector. Grit is particularly pervasive.

    My solution is to have two sets of thicknesser blades - keep the ones with nicks, etc and use them on salvaged timber for the first cut. I call them my sacrificial blades; a pedantic mate says that they are scrub blades. Then when I have surfaced all sides and am certain that there are no undetected nasties, I change to my smoothing blades and need only to take off a very light pass. Works well for me.

    And all that worry about missing a hidden nasty has gone.

    Love the character of salvaged timber. And the $$$'s.

    I use a Carbatech metal detector before chainsaw urban trees but like you say Graeme, metal is only part of the problem. The sorts of stuff I have found in trees includes; lumps of concrete, blue metal, a glass jar, an HV insulator, and pieces of brick. A soft iron nail, screw, or even a bolt doesn't actually do that much damaged to a chain cutter, mostly chains cuts straight through them and then you notice its not cutting quite as fast. A bit of filing fixes this pretty quickly, but things like tensile bolts, Tek Screws and those hardened screw profile nails can make a bit of a mess.

    Pearo,

    Went looking for the thread on using recycled timber and how you prepare it, so have a look at the last few posts in this thread.

    https://www.woodworkforums.com/showth...ecycled+timber

    It really depends on how much prep time you want to spend on the timber verses how much time you'll spend on fixing your thicky blades.

    I now have 3 TOWA L120 electric planers for taking off the surface (when one gets blunt blades I swap to the next), so no real down time.

    At the end of day when buzzer noise is not allowed I start sharpening all the baldes I dulled/nicked that day.

    ive bought metal detector from ali express.. and it was very cheap investment.. (about $11 USD which came up approx $13 AUD with free delivery)

    Used it few times and worked quite well.. looks very similar to carbatec model at less than half the price

    I used a compass for a long time

    just move it over the timber and if the needle moves - something ferrous

    I use an electric hand plane to strip recycled / painted timber before putting it through the machine. Works well for me.
