This is my first attempt at a horn bow, after making a few antler bows I got the itch to make a horn bow.  This was definitely a learning experience for me.  It took about a month of work just to get the bow ready for sinew.  The first two pics are about a day after the first 2 layers of sinew was applied, I waited for about a week then applied 2 more layers of sinew.  I am amazed on how much reflex these bows gained in a month after the sinew was applied.   Hopefully in about 7 months I will be posting pics for the finished bow.
