Another Tabletop Question - Individual Boards Instead Of Glue-ups

Hi all,

I'm aware of the fact that glue-ups react to RH along their width in the same way a single board does. To bypass this, I rip 1x4's to square up the edges and then glue them INDIVIDUALLY (and not to each other) to the apron so they will expand and contract respectively.

Is this sound logic? Given that the boards are butted tight against one another (see pic), it doesn't appear that there would be much room for movement so I'm confident I may be wrong.

Thanks!

If you glue them to the apron where it is running across the grain there will still be problems with expansion, contraction. Glue up the entire panel and then fasten to apron so it can move.

The metal clips are also available from Woodcraft. Do you have a WC store close to you?
I have one about 30 miles away. My wife wishes it was 300 miles away!

Gluing the boards to the skirt there is the potential of the boards splitting. It probably won't happen unless one of the boards has a crack in it already. What you need to worry about is over time when the boards shrink you may get 1/8" wide gaps between the boards. You would have been better off gluing the boards together and mounting it to the skirt in a manor which allows for shrinkage.

You have some pretty nasty cross grain scratches on the top. Since the wood has been stained it's difficult to sand those out. It would be a good idea to strip the stain off with some paint stripper so the stain doesn't gum up on the sandpaper. You can't just sand the spots. The entire top will need to be sanded to a uniform color and then stained again. If you just sand the spots it won't go as dark as it was and everywhere you worked on it will be lighter.

So long as the boards are the same species, they should expand and contract at the same rate. Therefore, glue them together, then attach them to the skirt with either z-clips or slots that will allow the top to move at a different rate than the skirts.
