I was gonna install a disappearing stairway for my shop. I have 11' ceilings so that stairway has to be made out of aluminum. $$$$
I think they can make them out of wood but the have special reinforcements which makes the prices just as high. $600 and up.
I can't believe you had to reinforce you lift. It looks plenty sturdy to me. I won't be as slick with the diamond plate however.
later...
