Hey Strangeways,
Hope you don't mind if I steal your idea - that's a great setup 
........Don't suppose I could get the dimensions off you? 
Go for it ! That's why I posted the pictures - so others can see how easy it was to make.
I started with the chipboard. Already cut in sheets of 1300 X 500. The rest of the build revolved around these sheets. I didn't cut any chipboard. The rest of the timber were bought in sizes of 1300 long by 19mm thick. There are two sizes, and I simply created two "boxes" without lids, and then placed 4 vertical pieces at my height requirement. I bought a box of 1/4 inch X 2 1/2 bolts (came with bolts) and washers separate. The wheels are the 55 Kg rated ones.
The bottom section can fit playfields, legs, etc.. I can also fit tubs of parts etc.
I pretty much "made it up" as I went along.
