When I get the top cap from Dave I would like to send the dimensions to you. If you have time and the inclination you could make drawing that would be great. Am in total agreement with you that the top cap will simplify the build from pipe tunnel standpoint.
Dwayne does Steve have drawings of wood fuse that would be awesome to have and use. I live about 1 hour from Huntsville and could meet Steve to obtain,buy,steal, or borrow

drawing, scan for distribition if he is willing to provide information.
