I invite you visit the Forums section of the Hydraulics & Pneumatics website at http://forums.hydraulicspneumatics.com/eve/forums
Here you will find hundreds of discussions on fluid power topics. Of course, like most discussion boards, you will find spammers who are only interested in promoting their products. This is not in keeping with the spirit of a true forum.
Whether you have questions, ideas, answers, or just an intelectual curiosity about fluid power, see our Forums.
