I got my knots in today and I was working on an Ever Ready 100. It soon was apparent that if I was going to get the loft I wanted, I would need to go through the existing shelf. So, I did and I've now got a hollow brush and I'm wondering if there are any good tips for making a shelf upon which I can epoxy the knot. I suppose I could just fill it with epoxy, but I'd rather not use that much epoxy just to fill a empty handle. Any tips, hints, special tricks, techniques, etc., etc.?
