It sure was full of voids! I finished the outside with CA and it took a good amount of time to fill the holes and sand it down again before applying the coats over everthing. I filled the inside ones where the knot hole was drilled with epoxy.I've made a few brushes with eucalyptus burl. Each blank I've used had large voids which I filled with epoxy before finishing the handle. Did you find this to be true as well?
