    Hi all – I’m building a new deck table that I’m planning on attaching to the base with buttons per normal, but I’m not sure how big to make them. I get that they need to allow for wood movement, but I’m really not sure how this table top will grow/shrink with humidity.

    Apologies for the potato quality photo – it looks better on my phone.

    The top is a laminated hexagon, cedar, ~36″ across the flats, and the base support will be square. I’m hoping for some advice on sizing the buttons – right now the rough plan is around 1.5″x1″ button, approx 3/8″ stub, approx 3/8″ deep groove in base.

    Does that seem reasonable for this kind of thing? Too big? Wood choice (oak maybe, cause I have some scraps laying about)? Just build it and don’t worry about it?

    Any advice would be appreciated.

    I think that your thoughts on attaching the top with buttons is about right but I have never used turn buttons on an outdoor project so my opinion is not based on very much. That is a beautiful table top by the way. It would be a shame to let it get rained on. — Jim
