MOVING RIVET JOINTS

V. Ryan © 2004 - 2008

 

If there is a need for a ‘pivot’, a joint that allows movement, consider using a riveted joint. Simply place a piece of paper between the two pieces of material and rivet them together.
The gap caused by the paper, allows the joint to move from side to side, a perfect pivot.

Below is a simple mechanical arm joined together with rivets. Each joint is movable because a piece of paper was placed between the plates whilst riveting. The arm has been designed to move the boxing glove forwards and backwards.

   
 
   

Plastics such as perspex can be riveted. However, use a soft rivet, one made from aluminium or copper. Steel is too strong and will cause the perspex to crack during the riveting process. Pop riveting is often used to join plastics, although modern glues are more effective.
