While delving into some metal working sites I came across these cool-looking tools for forming sheet metal: forming stakes. The above catalog picture shows some of the many shaped heads that are available for creating different shapes.
These Pexto sheet metal forming stakes from Roper Whitney are made from forged steel or cast iron. They fit into a socket on either a free-standing stake holder or a bench plate.
Forming stakes don’t come cheap — you’ll see a variety of stakes or heads individually priced from $100 to $400. Sets with holders are available, but given the individual pricing, the set pricing is going to be steep.
