Hello LJ’S, Looking for a bit of advice/experience. I am building a table top out of 2” thick book matched kiln dried Walnut. There is a knot on each side of the book matched table top with about a 4” crack from the drying process. My question is should I fill the crack w System 3 Epoxy? or inlay a butterfly across the crack to contain it, or maybe both?? The Walnut was kiln dried about 3 years ago so should be dry by now. I have no experience with this type of build & will appreciate any suggestions. Thanks in advance for your response.

I would do both. The epoxy will fill the crack. The butterfly will contain it and keep it from widening.

From what I’ve seen regarding this question: The suggestions to do both are what my first response was. A butterfly used to be called a Dutchman” as referenced to a functional repair. They have become symbols of added character, but it would really depend on the furniture style of the build.

I would practice doing both to see the results for myself in my skill in achieving it? LOL! And the overall look of the piece.

You also can insert an inlay of say, cherry to fill the crack. I have a 3” thick walnut desk on my project where I used a piece of cherry to fill the void. You mentioned 4” crack, do you mean 4” long or 4” wide?

Have to agree with DocSavage, if the look suits the build and you don’t mind the extra work, then go for it. From a structure standpoint (assuming the crack isn’t very wide) epoxy alone should suffice, and it could be dyed too.

Thanks Guys. I am going to use some Cherry inlays in some other cracks in these slabs, just didn’t know how that would work in a knot, the crack is 4” long, maybe a little over 1/8th wide. I think I have made up my mind to do butterflies & epoxy both. Only want to do it once if you know what I mean…........................Thanks
