I seriously think I might start and interest check and possibly a group buy for 7x costar wires. These things are way too hard to find
If you are going to do the IC and GB for Costar 7x, I would like to share the specification that I did for my prototype that I mentioned before.
Type of material: Stainless steel 304 wire
Size: 16 AWG (1.29mm)
Design
Test prototype on 16AWG stainless steel wire
Expected implementation problems:
+ 16 AWG Stainless steel 304 is very hard, as hard as hardened wire (music wire), so I don't think the E/Z Bender Wire Forming Tool (
http://shop.dubro.com/p/e-z-bender-wire-forming-tool) can bend it.
+ It seems Costar manufacturer has CNC bending machine, so if we are going to bend the wire manually, the combination pliers, heavy nose pliers, heavy vise should be used.
+ The Z-bend in the middle is the hardest part.
+ Each Costar 7x wire will need at least 190mm material.
