Answer 2

For my brothers birthday we built a half pipe whoea. Make sure you get good wood that won't worp in the rain. have fun

. Buy, borrow or download a "how to build a ramp" manual (unfortunately, the instructions are too complex to include on eHow). This will give you complete and comprehensive instructions, diagrams and hints on each step of building a ramp. There are several manuals readily available from skate magazines and Web sites.

2. Use the manual to determine your exact ramp specifications according to the space you have available and the type of halfpipe you want to build.

3. Estimate how much wood you will need. Consider if you want to double-ply the ramp for an extra-smooth riding surface. Also include the price of nails, screws and a layer of masonite for the ramp.

4. Contact all your friends who are going to be riding the ramp and explain (or hint) that those who help build the ramp are the ones most welcome to ride it. Ask people to bring tools. Try to find someone with a relative who is a carpenter or experienced woodworker and ask him or her to help, too.

5. Set aside some practical days to work on the ramp and let people know well ahead of time.

6. Get everything you need and everyone together at the building site and proceed in an orderly manner. Be in charge and delegate tasks to others. Keep people from goofing off and ask anyone who is not helping to leave.

7. Have a party when the ramp is done. Wheel out the barbecue and boom box for all of those who helped build.

8. Enjoy the ramp safely.

Tips:
As soon as the ramp is finished, establish a set of "ramp rules" and make sure everyone abides by them. Post the rules where everyone can see.

Most plywood is sold in 4-by-8-foot sheets, so it will save you some cutting if you plan your ramp accordingly: 12, 16, or 24 feet wide.


Warnings:
Have an experienced person do most of the woodcutting, to prevent costly mistakes.

Once you build a ramp, you are responsible for making sure nobody gets injured on it. Be strict about making people wear their pads and helmets.

Overall Warnings:
Skateboarding is an inherently dangerous activity that can result in serious injury or death. We recommend that you seek proper training and equipment before attempting this activity.
