Made a start on this bow yesterday. Just a young stem, which I split with the axe and then worked my way down with wedges. The Yew one...ahem... snapped. Gutted, but learnt plenty so now the first breaks out of the way I can crack on and keep trying till I get it right.
I've done some more searching and there is a surprising amount of good information out there regarding bows, so hopefully this one will work out.
