Debarkers

1/31/15       
Ken Member

To minimize the bandsaw blade wear & tear, we have a debarker unit attached to the head-rig of our bandsaw mill when cutting Northeast hardwoods (i.e. oak, maple, and ash). This debarker is a ¼ inch thick circular saw blade with carbide tips from Woodmizer.

When cutting a log, the debarker blade actually cuts a slit along the bark at the same height as the cutting blade, thereby minimizing the wear on the blade from cutting the bark, when entering the log.

Is it useful to have 2 debarkers on each side of the log cutting slits, so that the band blade would be free of bark on both ends of the log?

I would say a second debarker would do very little if anything to extend blade life. The teeth of the blade when they enter the log would find debris like dirt very abrasive. When the teeth exit the log debris would have no affect on the blade so long as the debris is no longer on the blade when it re-enters the log.

Shaun is dead wrong about this. I have often thought about adding a second debarker on the backside of my Baker 3630 E. Frozen dirt or embedded grit or rocks will dull your blade as fast on the back as the front. Steve C.

I bought a Baker 3638d about 13 years ago. I ordered the debarker on it , as well as the computer setworks. It "was" portable also. The debarker was completely useless and a waste of money. The blade was to small to cut deep enough on thick bark logs like Doug Fir and Incense Cedar, and wasn't powerfull enough for a bigger blade. Hopefully they have solved this problem by now. For many years now, any dirty logs either get peeled if the bark comes off fairly easy, or pressure washed, before they go on the mill. For me, it's worth the extra time, as I have a small market for the clean slabs. I think Steve has a point about frozen debris on the exit side of the cut. But if you are putting logs on your mill full of frozen mud and rocks, how long do the blades on the debarkers last? Just a thought. By the way Steve, if I may be off subject for a moment, how do you like your electric mill? When I bought my diesel mill, I wanted to be portable. I found out early on it is way cheaper and easier to bring the logs to the mill. I wish I had the electric mill now ( I think)!

I think I agree with the first Shaun. The reason the debarkers are on the enter side is so the debris does not get pulled into the log creating abrasive residue. When it passes thru the other side, it usually gets thrown outward.If you are worried about debris on the back of the log going around install a blade brush. I'm sure it will be a whole lot cheaper.

  • WOODWEB is a professional industrial woodworking site. Hobbyist and homeowner woodworking questions are inappropriate.
  • Messages should be kept reasonably short and on topic, relating to the focus of the forum. Responses should relate to the original question.
  • A valid email return address must be included with each message.
  • Advertising is inappropriate. The only exceptions are the Classified Ads Exchange, Machinery Exchange, Lumber Exchange, and Job Opportunities and Services Exchange. When posting listings in these areas, review the posting instructions carefully.
  • Subject lines may be edited for length and clarity.
  • "Cross posting" is not permitted. Choose the best forum for your question, and post your question at one forum only.
  • Messages requesting private responses will be removed - Forums are designed to provide information and assistance for all of our visitors. Private response requests are appropriate at WOODWEB's Exchanges and Job Opportunities and Services.
  • Messages that accuse businesses or individuals of alleged negative actions or behavior are inappropriate since WOODWEB is unable to verify or substantiate the claims.
  • 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.
  • Responses that initiate or support inappropriate and off-topic discussion of general politics detract from the professional woodworking focus of WOODWEB, and will be removed.

    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).

    The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards. Participants should undertake the use of machinery, materials and methods discussed at WOODWEB's Message Boards after considerate evaluation, and at their own risk.
