Ive never done this at all before, but i have an idea for somthing made from, probaby, about 1/2 inch round bar stock, formed into this kind of shape - Basically just curvey bar stock. Scale will maybe be lengths about 1.4m or so. Really i have no idea where to start. What i want to achieve is smooth natural looking bends - the bars will start at a base, all together, and end at specific places to support other items. Im not convinced 12.4mm bar stock will be enough to stop wobble / spring, but i cant see myself being able to bend thicker - if that! Can someone give me some pointers please?
