Hi Dave, The question was more about how to hold something like this to make it from scratch and there have been some great suggestions. Your method to repair would also work. At the moment, when I do use the tripod I can loosen the clamp screw, and push/pull on the rack to change the position. The crank just turns a pinion on a rack so it's easy. Which is probably why it hasn't been repaired in all these years.
