This came up in another thread and a few people have inquired about it. It's extremely easy to make, inexpensive, and works well.
Materials:
(1) 2"x8"x6'
(4) Wheels
Large screws
Each board (in this picture) is cut to 18". There is approximately 1/2" to 3/4" space between the two center ones. That's it! Easy peasy.
