I would like to take a 6’4" I have, and use it’s properties towards shaping a new scaled down 6’0" board. Not shape it out of the 6’4", but a completely different board, just keeping the same proportions. I don’t really know where to start though, and don’t really know how to change the measurements to be proportionally correct to a 6’0". Any ideas?? And is this done often (using proportions from larger boards and scaling them down to a smaller board). Thanks in advance.Brandon
