I'm stripping the deck of my Guillemot and the biggest problem I'm having is cutting coves in trimmed strips. I've tried 2 different files, a chainsaw file and a rat tail, and they just don't cut fast enough. I tried a ball cutter in a Dremel but it's really hard to control. I'm doing it now by using a box cutter to cut a "V" groove in the strip then dig it out and finish it off with the rat tail file. This works ok but I'm afraid if I keep doing that way there are stiches in my future. Is there a better way?
