I must be too hardcore for my own good then, because red locktite only worked for a while with mine. I upgraded now though, so I don't have to worry about the sad engineering behind the set screws. Still can't figure out why people would defend this design. I can only assume you have not owned a good rig with pin-through shafts.

Edit: Just out of curiosity, is anyone's argument that the set screws are actually better than pin-through?
