weinig powermat 1500 cut-stock tolerances

2/12/19       
keizzer Member

The company I work for has 2 weinig powermat 1500 moulders and we are concerned about our cutstock tolerances. We make our own cutstock in house and I was wondering what a how close we have to be to exact sizes before we feed it into the weinig. Any thoughts?

So for example if we had cutstock that was 2" wide 1/2" high, what would the tolerances need to be? 2" +/- ?.

First question is what are using to prep your blanks? Straight line rip saw or gang rip? Is the material really straight after that or does it have some crook in it from tension being released? I work with a lot of wood that once it's cut from a larger board, quite often it will have some crook. That means I need a little extra width to allow the molder to cut a good part. I typically go 1/4" over on width, I've heard of certain places that can go down to 1/8 or even 1/16, to me that's a little to close and may loose some lineal footage trying to save a nickel. What is your end product? Are you milling crown that has no give at all in a narrow piece? Flooring? That has some flex if your cutting tongue on the left, a little narrow on a few pieces won't kill anyone.

Our end products are window and door stile and rail parts. They have to be pretty much right on. I'm pretty sure that our bow tolerance is 1/8" over 2' length. Most of our profile shapes have to be within +/- 0.015" Not sure how much crook our cutstock has right now, but I know that it is gang ripped. I'll take some samples today and see how much crook is in them.

It is typical for 1/4" over on the width and 3/16" on the thickness because most people purchase four quarter 15/16" hit and miss lumber for 3/4" thickness mouldings.

Some mills, like Dustin mentioned mill less off each side and top, but they take the risk of reducing yield, which can be costly, you know, the old walk, "over a dollar to pic up a penny" slogan. Keep in mind the metal feed rollers that come standard on the moulder have 1/8" depth of tooth mark (penetration) that must be removed by the top cutter heads, you could use the knurled 1/32" penetration, or rubber rollers but you would sacrifice feed pull power on the machine, along with the added expense. You will have times where other rollers may come in handy, but try and stick with what comes with the machine, they work better than ever with the new gullet design.

If you set the in-feed fence at 4mm with 1/4" over-sized lumber, it should take out any bow that's 1/8" or less and still cleanup the edge. I have attached an article that may be of use to you with orientating of the lumber as you are feeding before it goes into the moulder.

Hope that helps some All the best Russ @ MR

  • 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.
  • Participants are encouraged to use their real name when posting. Intentionally using another persons name is prohibited, and posts of this nature will be removed at WOODWEB's discretion.

    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.
