Not from the UK, but he has videos on Utube showing step by step how to make his bows. Rock maple for the siyahs, and riser, and most important heat treated quality bamboo slats. He shows impressive arrow speeds with his bows that I have never been able to match. I think because of my short draw, and cheap bamboo slats. I make a beefier riser to cut a deep arrow shelf into mine. It is easier for me to shoot that way, and tunes easier. It is your bow, so you can make any mod you want to. Good luck on builds.
