II. Parts
Due to board sanding, there is a difference between actual size and listed size. For example, a board listed as 2" x 4" board might actually be 1.5" x 3.5". To see a list of actual sizes compared to list sizes, see Engineer's Edge.
You can often buy all these parts for less than $300 at Home Depot. You can just ask a local carpet vendor if they have any spare carpet you can have.
I recommend using screws instead of nails because screws pull boards together while nails tend to push them apart and knock of the levelness.
Cross-check my measurements; if you find any problems please email me at matthew.campbell@stanford.edu.
  1. Main Table Parts
    1. Side boards: (2x): 10 ft x 2x8 (Some individuals recommend using 2x10 side boards; this could help prevent balls from flying out but may make throwing them more difficult. If 2x10 boards are used, shorten legs by 1.5" and use a 2x6 for the angled backboard rather than a 2x4)
