I have some huge timbers from my 100+ year old barn that I want to make a cool cross country jump out of. Is it possible to make some sort of safe, but adjustable jump?

A couple companies make them. I think following this general design would be safe and appropriate:

I believe you can buy the hardware from the second company

That's so cool, but so expensive! Thanks for the link.

This is one of the greatest ideas for a cross country fences. I have jumped these jumps for years now, The ability to adjust the fence is great. You can start with it small to warm up and make it bigger. It is also great when jumping different levels in one group since you can just change the height depending on who is going to jump it. I most recently saw the Field Jump System used in the Derby Cross in Wellington, FL.

The system is definitely worth the money.

The jumps are also great to have at a ditch so you can make a trakenher of many different sizes!

I have several that are adjustable. They are essentially in a hogsback configuration with a captive rail on top that can be raised or lowered by how many blocks you use as spacers.

Here's one:

Here's another in the fence row

Both are made from free materials (except the fasteners).

Those look really interesting. We use to have cups like those for our stadium jumps.

I saw an awesome one years ago in the warmup at a HT in Germany. Let's see if I can explain this...

It's a coop. From the front, it looks like any normal coop. But, on the backside is a lever-arm and fits into slots on the base, which adjusts the height as the arm is inserted into different slots. The front piece is hinged at the bottom (big hinges) to allow the movement.

The lever-arm setup is like a lounge chair, like this... http://www.world-trades.com/pro/1079/1098-1/wooden-lounge-chair-487218.html

It was very cool! Let me know if I'm not being very clear :) The only drawback is that you obviously can only jump it from one side. But you could make the whole thing out of wood, with no special hardware and one person can adjust it...
