I need to build a mechanism to lift things with a servo motor. I’ve found this: http://technologystudent.com/cams/cam1.htm
I’v already done a simple one with cardboard and wood sticks, but I need something that holds the cam stronger. Right now the cam slips though the shaft when the object being lift is too heavy.
Where can I buy this components (like servocity.com) to assemble the mechanism? Or if the components are there, how do I assemble them?
Any help would be appreciated.
