Many thanks to my friend Bob Olson for helping me out! If you've got your own "Bob Olson" to help you, I highly recommend it.
We started with some plans written out. From those plans I bought all my supplies. But we ended up modifying the plans as we went along. The result was a unit that made better sense, especially when buying the supplies. For example, I originally wanted 8' x 30" shelves. But, since plywood is sold in 8' x 48" sheets, it was easier to make the shelves 8' x 24" instead (and it actually fits nicer in the basement anyway).
I've converted the parts list into a shopping list, since you can't buy all the lumber in the exact measurments that you need (unless you special order). Also, I already had a box of nails here, so I did not include the price below.
