DIY project: canoe dolly

My dad has a canoe being stored at his house that he uses time to time and decided that he didn't like carrying it from 1 place to another. After a little design work and a little time in his wood shop, he came up with a way to temporarily add wheels to his canoe to make for easier portages and to make those far off put-ins a little more accessible.

You can buy these things for anywhere between $50 to $200 or you can make your own. I'm sure dad didn't spend more than about $20 on this.

Tools required:
-Saw
-Drill and bits for pilot holes

Materials:
-All lumber 2X4
-Foam pipe insulation
-Hardware as noted
-ratchet type straps
-Wheels- whatever you can find, old bicycle, wheel barrow, high wheel lawn mower, etc. at least 12" in diameter, but not much more. Too large and it is hard to get the dolly under the canoe. Too small and one end drags the ground when you pick the other end up.
