Stic Post a picture of the maple with voids please.
This Osage had some cracks about 1/8" wide or so, I put some masking tape on the sides to keep in the epoxy
I mixed up some 2 ton epoxy and Acetone and worked it into the cracks

Knot hole on the other side.

Kirk this is real Turquoise chips (sand) , I reduced it down to fine sand.

spot drilled and filled the hole with super glue for a locator for the arrow.

I've used it for knot holes too
