Help!?

#1

I need some advice and hoped you can help…!

I’m making 1 or (hopefully) 2 End Grain Chopping boards from Walnut. All was going swimmingly until I did the crosscuts and discovered this horror within…

A load of pretty huge voids in the end grain, and therefore in the surface of the board, that go all the way through. So…the internet is (obviously) divided on the matter with some preferring Epoxy Resin, or melted Shellac sticks; obviously food safety is an issue. Or if nothing works then chopping them out and re-gluing is also a possibility I guess.

Any guidance much appreciated…!

I’m no expert, but I have made a walnut endgrain board once. I’d go for removing those blocks rather than filling. If the left and right sides are nice and square then you could cut roughly down the middle of the cracked piece and then glue those nice square left and right edges to each other.
