I bought some merino ram horn scales a while back to go on a drop point hunting knife for my son. While the scales will lay flat on the tang, the back side has several grooves of maybe 1/16 or a bit deeper in some spots. I don't see how these grooves/depressions will not be visible at the edges as gaps once final shaping occurs. The scales are 5/16" thick so i believe they'll end up to thin if I sand the backs to get rid of the grooves/depressions. That and I'd like to keep the knife hand around 5/8" to 3/4" thick. Has anyone ever tried to fill something like this with tinted epoxy? Unfortunately i don't have the scales with me to upload a pic that better shows the issue. Hoping someone has dealt with this before and understands what I'm trying to explain. Any suggestions?
