Building an IPO Wall......Need some advice - Page 1

Hi Everyone,
I'm building an IPO jump. Before I get started I have some questions. Hope you guys can help me.
I converted the metric measurements (December wide x 100cm high) to inches (59 1/16"  wide x 39 1/8" high).
I want to construct it out of 4" x 4" vinyl fence posts (will be vertical side supports), 2" x 6" redwood (will be horizontal base for vertical side supports), 1" schedule 40 PVC (will be top and bottom rails), and outdoor fabric (not sure yet of type), which will have a rod pockets so it can be hung to form the solid wall section. I'm trying to make it light enough to move around yet sturdy enough to withstand a hit and still be safe. 
Here are my questions;
How long would you make the base legs?
My club may want to use this in our up coming trial...so...because the fence posts are wider than the PVC will it still meet standard? Or do all vertical materials have to be the same width/thickness?
I want to make it adjustable...what increment adjustments do you recommend? I was thinking the first at 1' from the ground, then 6-8" vertical increments to the top.
The vinyl fence post will be capped at the top. These caps may stick up and inch higher than the solid wall section. Is this a problem? Will it make the wall non standard?

I built my teeter totter base in a design similar to what I have in mind for the Jump. Here's a picture of it.....Now envision this larger....with a solid section in the middle...and the base supports mounted underneath the vertical sides instead of at the sides as the picture shows.
  

Your opinions and suggestions would be most welcome.
Thanks,
Cheri

I would want it to be adjustable and have a place to attach bungee cords on the sides.

Cool teeter totter, clc.

Slam, what would the bungee cords be used for?

To teach the dog to stretch it's legs and clear the jump with out touching it.

Thanks andhourspass.

Jim....I'm not picturing it very well....can you describe it better?

The plans and sources of material on http://groups.yahoo.com/group/agility-equipment/ are worth checking. The folks there can be pretty ingenious.

I am assuming you mean the meter hurdle, not the A-frame wall?

If you want adjustibility you probably want to make it at 4 or 6 inch incriments down to about 1 foot off the ground for starting puppies.

If I understand Jim right I think he is suggesting having the ability to have the hurdle at top height but then be able to string a bungie cord or something flexible a few inches above that.  In IPO you will be pointed if your dog touches the hurdle in any manner, some dogs will get lazy about and then used to tapping their toes on the top board of the hurdle.  The bungie would discourage any touching of that top board and teach the dog to respect the hurdle and clear it without touching but without actually risking the dog smacking into that top board.
