I wanted to know what I could do to stop the checking in this piece of walnut? I’ve gotten the bandsaw box bug and picked this piece up from the offcut pile to make a small box with.

My original thinking was to sandwich the piece between two pieces of maple and then put some maple dust mixed with CA glue into the check for a combo design/stability.

Question being whether the CA glue will stop the checking?

Is the wood dry Steve? If it’s fairly well dried already, then chances are the checking is done. It probably occurred when the wood was green. Looks like the checking went pretty deep so I’m not sure if maple dust and CA would penetrate all the way down. I’d probably dye some epoxy and pour it in there if it were me. I think you’re probably just dealing with a design issue though rather than needing to stabilize it.

Just my $.02 of course! YMMV

Thanks Kenny. I’m pretty sure it’s dry, although I haven’t checked it with my meter.

I thought it was an interesting shape, so i grabbed it. I’ll try the epoxy route.

My experience is that medium thick CA glue stays fluid long enough to penetrate those cracks without a problem and usually stops further cracking. If you want to fill them with fine saw dust first I suggest using a combination of thin CA glue first to soak into the dust and immediately follow it with the medium glue. The thin glue acts as a wicking agent to draw the thicker glue in. It would be much easier than messy epoxy.

Use caution and good ventelation with this because if there is any moisture in the cracks the CA may produce fumes (sometimes visible smoke like vapor) that you do not want to breath.

Just for reference, CA glue is the same thing as super glue right?

Cyanoacrylate = Super Glue = CA Glue

BTW, My usual method of stopping checking is to cut the checked end off of the work piece, build the project, then seal with sanding sealer. This, of course, assumes you allowed enough waste material to sacrifice a couple inches off of the ends of your checked boards.
