I have a question about a brush that I thought I try to restore. I found it in a box of books I bought at auction. The brush is a Ever-Ready. My question is, while drilling out the knot my drill bit grabbed and cut right thru the stuff holding the knot. I now have a big hole in the center of my brush right into the hollow part of the handle. Do I just stop and throw this one away, or can it salvaged? I can post pics later tonignt if that would help.
