1)Print the plan on A3 printing paper. Cut the legs plan out , fold at the markers, back and forth to make easy hinge points.
Fold and stick the appropriate portions as per the hand drawn plan, matching the section numbers in the drawing with the section numbers in the printed plan. Now you have the legs. Make all eight of them.
Step 1: Make the Camshaft with the sturdy hubs
The CAM has 6 sections, each successive one at 120 degrees offset to the next. Thus it have three alligned pairs of sections. This allows to have atleast two pairs of legs supporting and moving the mechanism in sync all the time, thus making it stable.
Note: The sections labeled L/2 should have been L actually. Its a typo. There is no mistake in the plan itself. Only a labeling mistake.thanks.
