Mike Sheldrake needed a new board, so what did he do?
"After riding the same 8'6" Robert August board for 13 years, I found it had developed a lively flex zone somewhere near the middle, around the cracked and swollen stringer. It was time to strip the wax and send the board into wall-hanging retirement, but I couldn't afford a new board to replace it. Why not build my own? Could I do that for a couple hundred? I didn't want to work with foam. What about a hollow wood board? Hmm..."
He used cardboard!
I am amazed at the talent in this world.
