At the classic this spring a pin knot on my Osage bow popped and started to lift a little. I have a piece of back sinew and am ready to hit the pin knot with some super glue. My question is, should I sand the finish off the area that I plan to patch. I'm supposing the answer is yes, but just making sure. It is sealed with linseed or something similar. I'm trying to start this soon. I plan to strip the sinew and use gelatin for the hide glue. Hope everyone is having a gooder! Hanks for the info. dpg
