I have been working on a kitchen table for the last 4 years off an on. It is all air dried walnut and finally surfaced, it was way more work than I ever thought it would be. I have always used lumber from the local lumber shop, this was my first project that is from wood in a natural state. Dealing with cups, twists, and bows nearly drove me crazy, but I am finally do the point where I can build the table top. I have a few questions for the experts here. I would love any feedback. My plan is to edge join the planks with breadboard ends. Only three of the planks will stretch from end to end, most will be joined together in a parquet pattern.

Questions:
1) I plan on edge gluing the boards together with biscuits. Is that sufficient or would you suggest I cut a notch along each edge and glue in a piece of wood into each notch along the length of the boards.
2) Is glue and a biscuit enough to join the pieces end to end? Or do I need to so a mortise and tenon joint?
3) I like the look of the knots and bore holes in the wood, how do I best preserve them? fill them with clear epoxy?
4) What finish would you suggest for the top? Just a brush on poly? Or something thicker and tougher?

Thanks for any help, it is driving me a bit bonkers :-)

Hi Dave,

My thoughts:

1) Biscuits are fine for alignment but don’t really add any strength. Your strength is in the glue joint and yes, that’s plenty strong.
2) End-grain glue joints aren’t very strong but, with what you’re doing, each board will also be side glued to other boards so you should be fine. You could do M&T but IMHO it’s overkill. At most, I’d do a half-lap.
3) I don’t have much experience but the only knots I’ve ever tried to stabilize were with clear epoxy and so far they’ve held up fine.
4) I’d build several coats of poly for the finish. That should be good. I’d use a full-gloss for all but the last coat then use whatever you want the final sheen to be for the top coat.

One thing I forgot to mention… you’re Walnut looks an awful lot like Cherry. You sure it’s Walnut? I’ve never seen Walnut with that golden color. It’s a beautiful table either way, I was just curious.

Yeah it is walnut. It is just bad lighting and since it is air dried not kiln it has a wide color range. It certainly has the district smell of walnut when I am working with it.
