I can't see the photo, but i can point you towards what i see as the most common mistakes.
~make sure that you wrap the initial clapton in the opposite direction as you wrap the cores.
~if the cores bunch together, then the alien wire was stretched too far. If you stretched it too far, then you gotta use another piece, there's no going back. Either that or your swivels are janky.
~if the alien wire goes onto the cores in some crazy pattern, then it wasn't stretched enough. This can often be mitigated by simply squeezing the wire a little tighter while you feed it onto the cores.
~i hold my alien wire about 8-10 inches from the cores while i feed it on, i let the drill do the hard work.
~if your cores are tight and the alien wire is stretched properly, usually about 40°-45° is a good angle for me to hold the wire when feeding it on.
~holding the wire away from the cores lets the wire kinda self-adjust it's own tension and allows them to drop into place where they want to.
Hope that helps!
