Hi Terry
I am currently shooting a Meare Heath type bow made by Hilary Greenland. It im a wonderfull design when made well. You can find info on making one in Hilary's book The Traditional Archers Handbook (ISBN 0 9524 627 6 1) its worht having even if you dont make the bow,the chapter on arrows is worth it alone. Should be able to get it on amazon. The original Meare Heath was dug up just a few miles away from where i live on the somerset levels.
