Finally completed my uds. Been creeping around here for about a year now but never posted. What I did for my ball valve extension was remove the handle from the ball valve and connect a piece of threaded rod with a coupler and epoxy it all together. Worked out great. My UDS is currently on its mayden voyage smoking a fatty and some beans. Can't wait to try the food.
