Hinged flat top?
Has anyone hinged a flat top drum lid? I've seen several hinges for Weber type lids. I've built a basic UDS and was thinking of attaching a large strap hinge and just using pieces of flat metal as really thick washers to build up underneath the hinge so that I don't have to mess with the geometry/contours of the drum lid and sides. My top looks like this and was made using DWV grade copper.
