I wanted a paddle board. If you have been to a beach this summer you have seen someone on one. But even the very bottom end Stand Up Paddle board (hereafter SUP) starts at $350- and that is for a what is essentially a really big plastic milk jug. Plus, that hollow plastic weighs a crazy amount. Even the kids-size SUPs weigh more than my beach babes could possibly carry, strong as they are. Clearly, that is something we can make for ourselves. Come see.
Step 1: Balance
I have no illusions of actually using a SUP myself. The imitable Holly Mann (follow her at instructables.com/member/HollyMann if you don't already) could paddle one with her feet while standing on her hands, but I can't. My center of gravity is located just under my Adams apple because of my ponderous head (like a cake pop) and I will not be able to stay balanced on it. But a child would have a great time on one.
-One sheet rigid foam insulation 2" thick. ($25) but really it was free from Swap, who gave me a bunch of sheets he didn't need. I added some extra scrap to make it unnecessarily a bit longer. Boys are funny that way...
-Two tubes of construction adhesive $6 (the large ones. You'll be cutting them open so don't worry about a caulking gun)
-A fine notch plastic trowel $1.50
-A wood rasp. Garage sale price. Who on Earth know$?
-An optional 1/4" sheet of plywood (left over from a $8 sheet) for decking.
-Lots of heavy things for glue pressure. Sandbags work fine.
Total cost for DDC was low. You can buy everything you need for less than $50. But you will agree that price is only a small part of the cost for makers. The real cost- the only truly limited commodity- is time.
