I built one last week myself. I use a lot of sand paper at work, the ROS rolls going from 100 grit all the way up to 700 grit. After that the sand paper switches over to sheets. So I built a rack that has 4 dowels to hold 8 rolls of ROS sand paper. (2 side by side) Then 4 shelves to hold the sheets of sandpaper. I also made a shelf to hold my sanding block,and on the other side, a place to hold my can of polishing rouge/ I even added a holder to hold the brush to apply it to the the steel.
I have been using it for a week now and just love it. I am an organizing freak, so my set of pigeon holes before, just was not working. Now I need to make a new one for use at home. I'll snap a picture of it when I get to work next week. It really is a great design.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
