For the fourth project, we worked on a blister. We are suppose to create a dent on a piece of flat metal while keeping the rest of the metal flat. For this project, we used a mould of a teardrop carved out by the CNC machine.
Step 1: Create the model on grasshopper and import it into the CNC machines software.
Step 2: Wait for the machine to be done cutting.
Step 3: After the CNC machine is done with the mould, we have to use a handheld bench saw and cut out the centre piece.
Step 4: Sand down the edges and make it smooth.
Step 5: Clamp down the piece of aluminium in between the 2 mould.
Step 6: Start beating and expanding the metal in with a piece of scrap wood.
Step 7: If the piece of scrap wood is too big, sand it down to fit the shape you're working on.
Step 8: Continue beating.
Step 9: Beat down the sides of the blister to expand the metal downward and create a deeper drop.
Step 10: Keep beating the sides and the sharp end to make it deeper.
Step 11: After the desired depth is achieved, start to smoothen out the surface.
Step 12: Beat in the desired texture to make the shape less boring.
Step 13: Step back and admire the results.
