Built some recreational equipment this past weeekend. When I tore down the three rooms in the space I am renting, I kept all of the lumber and screws. I ended up using all of the screws and had to buy more. So far it has cost me 12 bucks! Woot!
I got the first layer of thin plywood down. Just have to get one more layer on it and it should be ready to ride. I have quite a few 2x4s left so I will probably make some kind of wedge to get speed, and put another quarter pipe after the fun box. This should be fun this winter.
