Hey Sam,

Here are two storage devices we have recently built. The first is a tree stand. It is a column made with two 2x4s with pieces of dowl protruding from the sides. A picture of the bottom detail is included. This stand is unique in that it is pressure fitted between the ceiling and floor. It is quite stable, (we were climbing it at one point), although we are going to widen the base to add some stability.

The second is a mobile bike rack. It is an A-frame design constructed with 2x4s. The top beam is a double 2x4. Casters are attached to the bottom, a picture of this detail is attached. It measures 8 feet wide, 6 feet deep and 6 feet 8 inches tall. Gussets are installed on the back. I would recommend also installing smaller gussets at the top of the frame, as well as adding another brace across the front on the bottom. Closing the frame on the bottom will add alot of stability.  The bikes are suspended from hooks which are attached to the rack with chains. This lets us slide them around which is nice.
