so my wife wanted something decent to rack her saddle on and challenged me to make something for as little money as possible. this design requires one 12x8 or 12x10 one inch thickness board, and three 3x8 one inch boards plus some screws, a robe hook, a saw, even a hand saw, drill and bits and optionally some stain/varnish
Step 1: Decisions about design
look at this frame- decide if you want a shelf below the center support, if you do then buy a 10 foot board, if you want it exactly like mine, get the 8 footer. you can salvage the wood for the top from pallets as i did or buy the three 3 inch boards. the shelf is a later addition and has proven good for holding brushes and the center support works great to rack the common green tool trays we all have around the barn.
