Veneering over large end grain conditions?

5/13/24       
Todd Kottke Member

I have been asked to repair two new end tables. The tables are glued-up solid oak and turned. The top surface has an 18" diameter with the base of 14". The bottom was not sealed by the manufacturer. There are cracks that have formed from the base moving upwards. The top had a sheet of oak veneer applied over the end grain of the turning. The sides and the top were sealed with a conversion varnish. The top veneer has raised and bubbled in areas about 3"x2".

I want to:
1. Remove the buckling veneer.
2. Sand the top flat and apply a wood backed oak veneer with a glue like titebond.
3. Fill the cracks with epoxy.
4. Seal the bottom with finish.
5. Re-finish the entire piece.

Will this "fix" result in the same buckling due to the large end grain condition? What would you recommend as an alternative?

I think we would need a picture to see what you're talking about

I think there is a high risk of failure again gluing to a large end grain surface area. I think you are right to use a cross banded veneer for the top. I would use a router and a frame to flatten the top as opposed to sanding to get a truly flat surface. Instead of PVA I would use epoxy for gluing the veneer. Oak end grain is a poor surface to glue.

I don't see how this isn't going to move again in the future based on the construction method. I think the only choice is to strip it and see the end grain. If you feel the need to veneer it, I hate to say it, but I'd use a bubble free backed sheet veneer, instead of a real raw veneer and contact cement it on, so it would allow it to move some. But it will never be what it should be, IMHO.

obvious manufacturing defect.

It's not clear to me exactly how the tables are constructed, but veneering over one side of an endgrain tabletop is asking for trouble both in terms of adhesion and wood movement. I would run away as fast as possible from this project.

They look like bad copies of Eames side tables. The glue ups werere probably not done well, hence the veneer.
If my guess is right it is all vertical grain, with hygroscopic movement in all horizontal directions. This movement will prevent the bad patch of veneer.
Now you know why the real deal are so expensive.

    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.

    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.
