As you know we are building Cadbike 31 for Aad. The CAD design is as good as finished, how to transform the sheetmetal parts from CAD to reality?

After the shape of the fender fit the buck Aad welded a 5mm round bead around the edge of the fender. We bent a pice of aluminum tube to fit the buck and then cut it in half with the bandsaw. The ends were rounded with a wooden hammer on a steel dolly. Aad welded tha half pipe onto the fender creating a tunnel for the wires of the taillight and adding a lot of strength. Just to see how far he could go with shaping the aluminum he polished the whole thing, no filler required!
