I am an aspiring customizer from a country where brand toys are really expensive (I could buy 180kg of bananas with the cost of a Studio Series leader at any local toy store). So a goal of mine is to create all my scratch builds using only junk parts and cheap chinese toys. I get my joints and hinges from lego clones and bionicle clones (bioniclones?) and those are good enough for small figures. But among my future projects I have leader or even bigger sized figures, and I feel those joints may not be strong enough to hold the weight of parts that big. As I don't plan to cut any big Transformers or Zoids toy for parts, I am looking for suggestions for cheap alternatives, be them stuff from the craft store, hardware store, or cheap toys that are known for very firm joints. Or maybe I should just try to make the fake lego joints stronger with floor polish?
