Thanks Collin, the pine sections are cut from a sheet of 18mm laminated pine and the ply is 12mm AA grade Marine Ply. Not sure where you are located but if you are from Oz it was all purchased from Bunnings.

Tip: Choose the pine sheets carefully, some are quite warped and when all glued together the stresses could cause the ply to delaminate. I found that out the hard way. lol.
