End being put on new stay (wire). Hydraulic cylinder (to the left of the photo) pulls the end fitting through the circular dies which press fit it onto the wire. It results in a very strong end to the wire, but not something that can be changed, or done at sea (there are other types of fittings that allow you to put ends on with wrenches).

This stay (wire) is being made to replace the wire that one old roller furling unit was on. It is a good idea to replace the wires when the roller furlers are replaced, since you can't inspect the wires after you put a roller furler on them.
