Bayonet Catch with Stainless Steel Spring and Swivels
This virtual workshop will focus on bayonet catches that include at least one swivel mechanism and a hand-made stainless steel spring that will provide tension for the locking mechanic within the catch. Through technical demonstrations, discussions, visual images, and an examination of various samples, special emphasis will be placed on problem-solving and creative applications useful to a variety of formats and approaches in constructing this type of catch. Engineering principles of these mechanisms will also be discussed, along with useful soldering and fabrication strategies, which can be applied to numerous procedures in the jewelry and metalsmithing studio.
Basic sawing, filing and soldering skills are necessary for this workshop.
