It's not necessarily that martial artists are not willing to share. It's just very difficult, in most cases, to describe forms or weapons techniques to someone who has not trained in a particular style or a weapon. For example: I have taught Kenpo for years, and over that time, have worked with a few weapons forms. I do best when I can teach someone directly, especially when they have a common point of reference.
The second way to do things, if you have no other way to learn, would be to pick up a video on the weapon, and learn the basics. Once you get those down (assuming you have a martial background, of course!!), then you should be able to put together at least a simple kata/form by stringing some of the basics together.
As you play and progress with the weapon, it would be increasingly more advantageous to get with others who already know it. Once you have a good feel for the weapon in its historical context (ie how it was used, how the katas were developed, etc.) and how it is used in its art, you can "adapt" it to your art. However, as with most other martial arts warnings, I would stress learning the basics as best you can, preferably with some supervision--just to make sure that you get the basics down.
Anyway, I don't think I'm telling you anything that you don't already know. Here is a link for at least one starting point, where you can get a "how-to" video along with a soft foam three-section staff:

Give it a try, and let me know what you find!!
