About this blog

A "Dynamic Response Test" has been created to compare properties of several Carbon Tubes.

Specifications for carbon tubing that you purchase for the purpose of constructing a frame yourself, or for modifying an existing frame, only include tube ID and OD dimensions, and an overall weight. Some tubes and frame sets will only provide a model ID and no other information.  The more experience kite flier or builder will be interested in more information than this.  Hopefully the tests that I have conducted will be useful to you although you will see from the pictures that I don’t have a NIST certified lab.  I was able to conduct these tests with readily available household items (for me, they were readily available :)).

Nail Boards for Knot Tying

I was inspired by the information shared in recent posts regarding the existence of something called a "Nail Board" to help tie accurate "Knot Systems" such as bridles, leader lines for handles and potentially other applications.  I decided that what I am about to share is too lengthy for a forum post so I have posted this as a blog instead.  I hope you find it useful.

Carbon Tubing Dynamic Response Test

Summary: A static deflection test was previously performed on several carbon tubes allowing them to be compared based solely on “stiffness”, or the “spring constant” for each tube.  A link to the discussion can be found here: http://kitelife.com/forum/topic/7329-carbon-tubing-comparison/ Experienced Rev fliers have responded with comments regarding the “reflex”, or response of the carbon tube frame being more important than the “stiffness” or weight of the frame.  Experience
