Aliens are deceptive in nature. Will get there eventually.View attachment 118629
Ahhhhhh, the frustration named Alien Clapton... Been there many times and I will say that practice, practice and a little more practice will get you there eventually.
I found the biggest thing holding me back was proper preparation. If your prep is done right and you've got your key rings (in my case lego blocks) keeping your wires parallel then your 90% there to making perfect Aliens.
That and keeping the right tension on the Alien wire as it's wrapping are the keys to getting my Aliens perfect.
EDIT: I noticed from the pic that your Alien wraps are quite spaced. This will happen if your leading the wrap as it goes. Keeping back a tad will result in tighter wraps.
Just my 2c - I hope it helps you
