A local retired gentlemen likes to build a couple bows over the winter months. He uses materials that are from his land as well as bamboo. I was lucky enough to meet him a few months ago. I found out he made bows and asked if he would make me one. He said yes and this is the result:
The riser is made from osage that was buried in a creek bank for 30 years, hence the green color. The limb veneers are from a maple tree that was in his front yard. The limb cores are bamboo. It shoots fantastic. Fast enough, forgiving... A great bow!
