In industry, there are also some very powerful, automated machines, that do the job of the craftsmen, spinning items in just seconds or less. Cylindrical shapes made by spinners were important additions to airplane manufacturers, who needed nose cones and props containing no seams, which could possibly fracture under stress. Some well known Spinners in history would include Thomas Jefferson and Paul Revere. Today, there are very few people who know how to spin metal, and sadly, many fewer who actively spin. In the state of Maine, it is estimated that there are only about 12 people who can spin metal, and of those 12, maybe 4 who are active spinners.
Metal spinning is a dying craft.
I would like to hear from you.
