Park Plans
The picture below this writing is probably  the best fingerboard park plans I have ever seen. This park features every thing from a halfpipe to just a single rail. It shows you pretty much the perfect skate park, and every thing in it is possible for you to make. Check the tips underneeth the pisture as well and you will find that it could be pretty helpfull...
- What ever people say, balsa wood is not good for skate parks for the following reasons: too expensive, to flimsy, you can't get it in very big perportions, breaks extremely easily, too fragile.

Trust me on this one, the best thing to use is shoe boxes, cardboard, cereal boxes, and thin ripple cardboar,(which is what I made my massive skate park out of)

- The best things to use for rails that you don't have to pay for is a brass coat hanger, all though if you live near a hobby hous, they sell hollow aluminum tubes, and they are long and bend able, also perfect for the job, you can make and bend them  in just about any way to form any sort of rail you want, whether it being a railing on the side of steps, or just a single rail to ollie on to. 

-Halfpipes are probably the biggest things in your home made skatepark, well to me it is the most important. Again the best thing to use is a cereal box, and an old ripple cardboard box behind it for support. What you can also do is take a thin straw and glue it onto the edge of the pipe on a perfect 45 angle so you could make it easier for you to grind.

- Suping it up is a big thing forthe park. I suggest  using paper to cover the ramps, or paint it comething like black. To get the access glue off the ramp, hot glue I mean, use sand paper to sand it off slitely. Don't try to peel it off, or the rest will come with it!!!

- A big thing in a park is always the small things, like a grind box. They are the simplest things to make and the best things to prastice your grinds on. What I did was take an old crayola pencil crayon box and ripped off the loose peice at the top of the box. Cover the thing with white paper and use electrical tape, black preferably, and tape it to the ground like you would with ramp tape. You could make one out of just about any thing, the best thing to look for is if you could boardslide, and if the side that you're grinding on isn't sharp enough to ruin your deck.

-Fun box's. They are a pretty big thing in fingerboard parks. To make one is pretty difficult if you want it to look amazing. Take a shoe box and use jenga blocks glued together to make the stairs. Make 2 curved ramps and place one on each long side aroud just as long as the shoebox. Then make a flat ramp and place it on one of the small sides. Then make the stairs and glue them onto the other small side. By now each side should be glued to something. For a little grind box on the flat ramp just do the same thing as you would making a single grind box on the ground, only  make it smaller and make sure that it is secure on the flat eamp. From there just put a rail or something going down the side of the flight of stairs by using an old brass coat hanger. These blue prints below may be a little usefull.
