Metal Detector For Staples!

I plane alot of rough sawn clear cedar, and I'm getting tired of ruining my knives when hitting staples, even after we check and double check for them! Just dropped off 3 sets of knives for sharpening and it's getting old so old.

So I need a better detector the the cheap harbor freight one I have, hopefully one that's specifically for scanning rough lumber. Would anyone have any suggestions for me?

another question, we often find little round pieces of something hard embedded in the lumber that's also chipping the knives I bet, what is that, road grit from Canada?

The grit is small bits of gravel coming from the forks and yard of the folks that handle the Cedar before you get it. Watch how the handle it, often setting one end in the gravel, then picking it up again. This puts hundreds of little bits into the wood, to be found by your knives.
Do not set lumber on a concrete floor when storing, or it will pick up grit and nick the knives.
Carbide? Talk to Russ and see what he has to suggest.

David, I've heard carbide knives aren't as sharp as regular steel knives, and therefore not the best choice for planning soft wr cedar?

It is true that carbide does not have as sharp of a cutting edge as HSS. For many species of wood, HSS knives are a better choice. Poplar, many pines, firs and many cedars will finish better with steel versus carbide.

I teach it this way , the softer the wood the more you want to slice it , the harder the wood the more you want to scrap it. With this said using steel for soft to cut woods generally works better. With the introduction of DGK, a DLC coating you can achieve the finish quality of steel with the life of the tool that will approach that of carbide.

Do you have a link for those DGK knives? When I google it all I see is Dirty Ghetto Kids :-)

I'm not sure where it's made, but we use a Garrett metal detector purchased from Amazon. It works great, even on "cut-backs" (i.e. 9' boards in a 10' pack).

However, I have this tidbit to add. We have long been annoyed by staples in wood. The metal detector was Step 1. Then we found a company that had developed Composite Staples - you can machine them with no damage to woodworking tools! Rather than wait for the Trickle Down effect, I decided that we would take the helm and show our suppliers that our money was where our mouth was, and we Wanted Composite Staples. So we bought the Special Gun (about double the price of a regular one) and bought a case of staples (more than double - don't remember off-hand) and started using them.

First impression - good. They worked every bit as good as metal ones.

However, one of our suppliers started using composite staples last year. Since they have no Iron in them, the Metal Detector doesn't detect them (d'oh!), so we don't even bother. However, the ones that this particular supplier is using are hard enough that they wreak havoc on our HSS and even Carbide Insert knives... Not as catastrophic as standard metal staples, but it would almost be better if they were, because it makes someone wonder "is this bad enough to have to do something about?!!"..

  • Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
  • Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).
