Things you will need:
flat head shovels
3-5 gl. buckets
Tips on building:
Don't cut down trees to make your lines. Choose an approiate spot in the woods large enough to build jumps in the first place.
Plan for the future. As you get better you will want to make them bigger. It's a simple process of making a jump bigger; just takes hard work.
Use logs and such to make the base's of your lips and landers, it will save you a shit ton of time in the long run digging.
Get rid of any rocks in your jumps, they'll hurt if you don't.
Dig drainage out of your pits, so you can be right back to riding after it rains.
Spray your lips down with water before every session to keep them well packed.
Dig before you ride every session so they stay maintained.
If you have acess to a blow torch use it on the lips to avoid cracking.
Build the lips next to the trees so they have a solid base and that way your not chopping up all the roots and killing the tree and causing the soil to erode easier.
Start small, a beginner doesnt need anything bigger than 4 ft tall and 10ft long to learn on.
Make sure you have enough of a runway before the first jump, not just for the one your building now, but for your eventual monstorous doubles.
Once you do build some huge lines, build a couple of little beginner doubles or tables for unexperienced riders to learn on so they can eventually be another set of hands to help dig.
10 DIRT JUMP COMMANDMENTS !!!
Some basic guidelines for public dirt jumps. Maybe you'll find these helpful. Maybe you won't. Very few people know any of this. Remind your fellow rider so next time he can't say he didn't know. Feel free to cut/paste/adjust/repost... SPREAD THE WORD !!!
1. If you enjoy riding your local dirt jumps, then CONTRIBUTE. Give something back. Don't just show up, tear it up, and split. Repairing your own damage is MANDATORY. If you mess it up, FIX it. If you take a chunk out of a landing, FIX it. (If you don't know how, ask).
2. DON'T LITTER !!! This is only one of many ways dirt jumps get torn down. Don't bury it. Use a trash can. Trash looks horrible.
3. DIGGING means to dig new dirt and maintain the trails. It does not mean "re-shaping" things you don't like or "don't flow" for you. Lip shapes and transitions are the privilege of the builders. If the builders like steep lips/landings, that's how it is.
4. If you show up to a spot while people are digging, then you dig BEFORE riding. This applies to everyone. If you show up and the Diggers aren't there, then you can water the jumps before riding, that's it. DO NOT CHANGE ANYTHING.
5. MAINTENANCE is watering, sweeping, picking up trash, raking, packing, etc. (Sweeping dust off dry jumps is not as good as actually watering it, which will settle the dust and re-pack it when ridden).
6. Riding is done AFTER you have demonstrated appropriate willingness to contribute to the trails.
7. DON'T ride when it's muddy. It tears the jumps up, and pointless anyway. Be patient. DON'T create more work for everybody.
8. ABSOLUTELY NO motorized vehicles of any kind. No 50's mini bikes, quads, dirt-bikes, RC cars, etc.
9. Dirt Jumps are NOT a playground, and little kids should NOT be running up and down lips/landings like they're at a McDonald's Play Palace.
10. BE RESPECTFUL-Can't be said enough. Be respectful to the builders, neighbors, other riders, and the Earth. If you're respectful, you won't get disrespected. Period. Don't be a loud, littering, selfish guy with an attitude. Thanks.
