Kerry some things and procedures one rediscovers even though one knew about them.
Until recently, I did not understand the function of Eckold tools for spherical surfaces. Only after I was must fixed "all" them, I was surprised how beautiful they work. it was in a situation where I needed to shape stainless steel for the sink and I needed to have soft sheet metal and good shape.
But I've been using a "hockey" rubber puck for a long time. It lifts the material where you need it completely reliably.
Can you take a picture of the set?
