I just roughed out a Meare Heath designed bow that was found in the pete bogs of England that was made roughly 2600 years BC according to experts. It was a broken bow that contained part of the handle ,and one limb. It is 75 inches long, 2, and half inches wide most of the length of the limbs, and tapers at the tips. The real deal was made with English yew. I used black locust, because it is what I had at hand. If I would have had a good piece of birch that would be what I would have used because of it's light mass. The rough cut bow is currently drying. I went to Utube, and saw a few well made examples by an English bowyer. The bow seems like it will be really heavy, and come with an excessive amount of hand shock by it's very design. Has any of you on this sight made ,and shot one? Just curious as to what results you may have had. Can't wait to finish mine, and get shooting it. Bob.
