The Sirhowy Wyvern in progress, 3m L x 2 m H. A tunnel runs under the horse with carved images on it’s walls so we needed access to it. A thin support wall blocks the tunnel half way. It supports the structure but allows us to crawl in do the art-work ( a lot was done by some fab children) The support was discarded when we cut the sections. We didn’t get to see the tunnel right through until it was installed on site.
