I just finished building a cutting board that I’m giving to a friend at work and I noticed two very small defects in the walnut that require some attention. If I fill them with Epoxy, how will that repair look once Mineral Oil is applied? Another thought I had is to just take some sawdust and mix it with some Tiitebond III and glop it in the cracks and sand it flush when dry. This actually might be a better solution but I just want to get some opinions. If you all do recommend Expoxy can I get away with the regular 10/20/30 min Expoxy?

- Knockonit

you’re saying ignore them and go about the finishing process? Shouldnt I be concerned about bacteria getting trapped in those cracks?

I’d leave it alone as well… epoxy would make them stand out even more.

Pack them full of walnut sanding dust, drizzle with thin CA and then sand flush. Will look just like a solid knot in the wood. No chance of anything getting stuck in the hole.

I’d rather eat more bacteria then epoxy.
leave it but pack some salt in there to bring out the flavors of the bacteria :)

5 minute epoxy should work just fine. I use it all the time for small chip-outs and small defects like yours. You can use it clear or add a very small amount of walnut sanding dust for color. Experiment a little. More than a small amount will make it too dark. While it sets up in about 5 minutes, let it cure for 8 hours or so before sanding.

I’d have no problem filling it with either sawdust and CA glue or epoxy. Both would end up looking fine.

If you are going to try to fill it, use epoxy putty. It will have a softer sheen than regular two-part. Also, do follow AlaskaGuy’s advice and test it first. From the looks of those defects, you might have to dig into them a bit in order for the epoxy to have something to grip

After looking at your photo a second time Scotty the small inclusions don’t really matter.
You have long grain mixed in with end grain. The project is doomed to fail
All the grain needs to run in the same direction esp with a cutting board because it will cycle from wet to dry.

It all looks like end grain to me.

If it fails. It’s because you didn’t use alder.

Does look like end grain walnut with long-grained maple?

Epoxy will fill the hole, but it will be very noticeable. I’d go for the sawdust and glue or else buy a tube of walnut wood filler at the BBS. Basically, it’s the same thing.

I just filled a bunch of larger holes in a walnut project with a 2 part wood filler epoxy and you can see every one of them. Fortunately, it will be stained ebony the epoxy will take a stain.
