So the Question is, I want to make a gib for a project that is still in the dreaming stages of design. What is a good material to use? It is a straight gib with set screws to adjust and will be running against cast iron. Steel, bronze, brass, all come to mind but I think I sure would like some advice before I dive in to this. If the project becomes feasible in respect to the skills I have or have access to I will start a new thread.
