Gents,
Pic #3 shows the ring being soldered on. The arrangement of the EK frames in progress is probably just the way that manufacturor developed to do that particular job. The other photo shows thw same process but with the frames arranged differently. Different way of doing, same results. Maybe an individual preference of the craftsman doing the work at hand.
Applying flux to solder the frames together when the frames are overlapped like in pic #3 would cause an unnecessary cleanup later on in the process. Flux is used where one wants the solder to flow. Overlapping the frames like shown makes more sense in spot soldering the rings only. A better use of conscentrated heat.
Some manufacturors hand cut the frames, others used shearing dies to remove excess material.
The picture Biro posted of the assembly progression explains the process clearly.
Great thread!
