Screw It or Glue It: Fastening and Joining Parts
Probably 90% of a moving mechanism doesn’t actually move. What? Well think about it – most moving things, let’s say a blender, have a small moving part and a lot of structural support around it. This chapter will cover fastening and joining techniques to help make the structures of your moving parts sound and sturdy. We’ll focus mostly on construction techniques and non-permanent joints (screws, pins) vs. permanent joints (welds, rivets) because they’re easier to prototype with and don’t require special equipment.
