im thinking about building a jump or a drop off, any ideas?

Since the details to build a really good jump with a decent tranny are pretty technical the easiest place to find an answer to that is bmx websites. Do a google for "bmx dirt jumps" or anything to that degree and you ahouls find something :)

Hey BB69, how big do you want to go?
What we usually do is find a decent dirt lot that is not being used, bring some shovels and start building. That way you can make them how you like. 1' to whatever in size, add a kicker, make it rollable or drop off. What ever you want.
When you start getting into the bigger stuff you can get some old railroad ties and sand bags to build up a base and then cover it with dirt.
Just start playing around with different styles and hights and practice on them.

You posted while I was typing. Is this something you want to be able to move or will it be stationary?

this is something i want to be able to move, i have this long run way beside my house about 80meters that goes to the curb on to the street and i want to put the jump on the curb so i can jump onto the street.

Well there ya go. Just get some 2x4's, some wood screws and a 4x8 sheet of 1/4 plywood and have at it.
You could even cut the width in half and build two ramps 2' wide and have your self a tranny.

Here's a tip, if you want your ramp to curve, take the sheet of plywood and soak it for a few days. It'll become like a wet noodle and you can shape it easier. Then when it dries, it'll be smooth, yet curved with no harsh sections. I throw it in a neighbors pool overnight (Obviously with permission).
Just build the subframe correctly, and the plywood will mold to the subframe!
