I’ve used a lot of maple and Walnut together. Not seen any glue joint failures…

I had a similiar thought several years ago. I wanted oak to be visible and yet I didn’t want to use a lot of oak that was hidden. I glued yellow pine to the oak. I attached the yellow pine and left the oak exposed and covered the pine with some more trim. This has been in place for about 9 years. Works so far.

I’m guessing that most woods will do fine together, but a lot of it would have to do with technique. I imagine veneering to plywood is more appropriate then solid wood. One would also have to take into account the movement of wood before implementing a design.

Has anyone seen any woods that expand and shrink a lot throughout the seasons to make it very unstable?

I’ve not had an issue but I believe some have when they’ve been trying to glue a really oily exotic wood to something else. A lot of suggestions I’ve seen is to use acetone or denat alcohol on the surface, then apply the glue.

SSM, good info, would never even have thought twice about it

My guess is most woods won’t give you much problems. Aesthetically, it’s a matter of personal choice. Structurally, I try not to mix woods that are dramatically different in hardness.

Also, sometimes the movement could be radically different, and how that might vary with the glue up, but nothing’s coming to mind.

Personally, I also prefer my woods to be woods that grow together (in other words, latin american woods with latin american woods, maple, walnut, oak, etc. with others that are local for me, and so on..) Though I CAN mix maple with purpleheart and sapele, for some reason, it feels wrong. There are some exceptions, but….

Thanks guys. Understanding what is an oily wood is one thing I should keep an eye out for. I could see Olive wood being oily. I wonder about other nut trees like walnut, Pecan, almond, etc? Thanks SSM

Bob, I also have difficulty justifying putting some woods together that don’t naturally appear in the same geographic region let alone continent. I could imagine a good argument about cross breeding, uniformity, similar climates and ecosystems but still an interesting topic of artistic choice. I wonder if this has been debated with the particular styles of furniture (shaker, arts and crafts, Greene and Greene).
