Keep in mind that new jumps will have soft faces. It takes a while for the jump to 'settle in'. Guess it depends on the type of dirt you are working with. I find it difficult to judge how far apart doubles/whoops/singles to table tops should be. And how large a jump is needed for the particular situation. Also, you do not want friends or youself getting hurt. Starting with smaller obsticles then adding dirt to them is one way to build up your skills, help keep people from getting hurt and also to determine what you really wanted to accomplish. Some things I have imagined in my head, don't work out that way. Other things that were just last minute or no planning evolve into favorite obsticles.
A favorite jump I have is a single with about a 20' gap onto a 40' table top. It allows better people to clear the entire table top and lesser people to land on top of the table top.
Some things I have found out:
1. moving dirt is hard work
2. it is time consuming
3. quite a bit of anxiety figuring out how to do what you imagine
4. heavy equipment is dangerous and it is easier than you think to get in trouble
5. there is never as much dirt in your bucket as you think
6. wet dirt is very, very heavy
7. finding the dirt to use is not easy. If you dig a hole, then someone may fall in it. If you scrape the ground, it becomes lower than the surrounding ground and ends up being a mud puddle. buying dirt is expensive.
8. your friends complain that its too big, too small, ruined a good straight a way, should have been here or over there. but you like it just the way it is...
9. having two tractors would be reallllllly great. yours and a guest tractor :eek:
10. creating jumps, etc IS ALMOST AS MUCH FUN AS RIDING :)
Welcome to the never ending world of track maintenance and repair.
oh yeah, wish I could afford a watering system........
