2" cove shaper

Do you guys know which manufacturer sells a 2" cove shaper tool? Bore needs to be 1.25". I assume Freeborn could make it custom, but I am hoping somebody here knows a manufacturer of this tool that has it readily available. Thank you.

Corrugated head and ground knife? How deep is the cove? Running vertical?

To clarify, the profile is simply a convex quarter-round cutter, with 2" radius. These are not corrugated inserts typically, but a very large brazed tool. The corrugated ones would be more like a molder knife for crowns and what-not.

If you have corrugated heads you can order the knives easily. Probably wouldn't spin them faster than about 5,000, on a heavy shaper with power feed.

I just checked my normal suppliers, looks like corrugated is the direction you are going to have to go. You could go with a brazed cutter but would cost a lot more. What wood are you cutting and how many running feet?

Depending on how many LF you plan on making you might be able to get away with a router bit. Again, not sure if you are saying a 2"R or a 2"D

I have the 1 5/8" version and it was a nice cutter.

I don't know your experience with corrugated knives but a few things to take note of: There are many different grades of steel available. The price goes up with the usually harder alloys. But so does wear resistance. On the other hand the hard alloys are also more chip prone when they hit sand or other contaminates. They cost more to grind. So what you order depends on several things: the amount of molding to be run, what are your options if the knives get nicked during a run, do you have a profile grinder to touch them up. I've got a grinder so would be inclined to order knives roughed out because there is so much material to be removed on a 2" radius.

Thought I had a winner, 2" radius but is more of a thumbnail. If your interested cover the shipping and you can use it.

Steve Juhasz, I just looked at your web site, very nice work.

Thank you to all those who responded especially JL who offered to lend me the tool. However, turns out the customer was after 7/8" radius, and what we normally call cove and bead, in order to produce fitting 1 3/4" diameter half-round edges of boards for fitting together in a wood tub. This is one reason I always send a scaled drawing for approval before even quoting this type of project.

    FORUM GUIDELINES: Please review the guidelines below before posting at WOODWEB's Interactive Message Boards (return to top)

  • 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.
  • Comments, questions, or criticisms regarding Forum policies should be directed to WOODWEB's Systems Administrator

    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.
