Got the casters bolted up and the shelves cut out of 1/2" OSB tonight. The cart rolls around very nicely. I'll start sorting thru the scrap pile tomorrow. ;D

I have to get all of my buckets emptied out so I start sorting...

I still have one shelf to make. The lower one in between the 2 x 2's

I think this will be a much better solution to storing my cut-offs then piling them on the floor.
