The finished product looks too pretty for its purpose. I made one a while back using the same plans but with more industrial looking pipe and unions (no gold endcaps and non-taped pipes). I just painted mine black and it works perfectly. This is really a question of form over form, in other words, this is going to be under the camera, not in front of it.
please please please learn better english before posting an instructable... a list to accompany pictures would be preferred for materials... and proper spelling of steadicam
