One of the rewards of never throwing anything away is that you can always find something to help you fabricate something. I found a bed frame support leg in my one of my boxes of metal stuff. It's a 1 1/4" tube with threaded caps pressed in each end. The threads take a 5/8" threaded rod. I picked up a standard hinge at Lowes, some spare 5/8" rod from my junk box, and made the foot from another piece of spare metal. I'll mount the hinge to the bottom of the first step. The hinge allows you to fold the leg down for support and up against the bottom of the step for storage. 1/18/14...fabricated and painted the support. Now all I have to do is mount and figure out how to secure the support for storage. "Watch this space."
