I sanded the whole bow down after filing in my belly grooves. I went down to 120 grit for now. Its time for skins. I had a chunk of Timber Rattler laying around that was 18" long. I split the skin and had just enough to cover my sinew, how cool is that! Skins are very easy to apply to any bow. A few basic tools are needed. A bucket, pan or bowel of water, bath towel, glue and some skins. The first thing I do is drop the skins in water. Then spread glue evenly and completely over one limb. By the time Im done with that the skin is ready to come out.
