Title: 90° rotating arm
Post by: dmehling on May 09, 2008, 12:17:45 PM

I'm trying to build a rotating arm with a 90° angle attached to a servo.  To better understand what I'm trying to do see my attached diagram.  I was wondering if these 90° tube clamps would do the job:

I would have one of the clamps attached to the servo shaft with an aluminum tube extending perpendicularly and a second clamp attached to the end of that with another aluminum tube attached.  Has anyone used these clamps before?  How powerful of a servo would I need if the two aluminum tubes were about 8 inches long?
