This is a rough instruction for making a set of dies for putting on tips on spiral steels, used in corsetry.
I have made at set of dies for 7mm spiral steel, to be used in the prym setter. Print them in a 3D printer and stuff them into your prym setter and make lovely tipped spiral steel boning for your corsets.
This is version 2.0, as the top die was to narrow for the setter, and got pushed out through the hole in the setter. The new file tippress top2.stl does not have this risk. I will upload a new picture when I print the new top next week.
