I've seen them up close at Noyes Camp in Spain. Unlike me, J-W does not hand-file bits of scrap iron in his garden shed. J-W's world is inhabited by robots wielding surgical instruments. J-W utilizes only refined high-tech alloys. These new wheels are as state-of-the-art as can be. The prototypes fitted here to Tom's awesome J&M framed Sportser were machined from spun blanks, but the production versions would look identical but be forged.
