How to Make a Steadicam� Iso-Elastic Arm From K'nex

A steadicam® is basically a Device that allows a camera operator to cancel out the camera jolt as he takes a step. 

Having searched the web, I have found many tutorials showing how to build the sled, but not the Iso-Elastic arm that attaches to it. On my budget, I found them quite expensive(even just the sled). So I decided to design and build one out of K'nex. Anyone who knows anything about how they work, will see the support mechanism (elastic band) I used in the arm is similar to the original design, but got replaced, because of it's in-ability to be adjusted in terms of strength (which is necessary when using multiple cameras with different weights on the same appliance). I did try the new, adjustable method, but it didn't work very well because of the limited pieces K'nex has invented to use. Also, as I have not designed a gimbal either, the footage will not be industry standard smooth.

Also: the Arm does not fully take the weight of the camera and sled (in my case a tripod), and it is not designed to because K'nex does not have that weight support capability( also because I did not design a body vest). But if built and used correctly. your camera and sled/tripod will be noticeably lighter in use, and the footage will be relieved of that annoying jolt every time you take a step.

Edit:
I have Finished the V2 version and am about to post some photos of it. (V2 has strength improvements) (V3 Will have Arm-to-belt connection improvements. V3 Is Currently in the Design process)
