Holding tension in the right places is how I finally figured out how to get good contact coils without the spacing. I hold the screwdriver in my left hand and squeeze the beginning of the wire into the grip with my thumb
Then I “fold” the wire over the screwdriver and while keeping the pressure with my thumb, I use my index finger and press it into to loop I just made so that there is no chance of it springing back or losing tension
Then I just “fold” the wire back back over the screwdriver and slide my thumb down to keep the pressure on the wrap that I’m folding, alternating between using my thumb on the “fold over” and index finger on the “fold under”. As long as you keep pressure on the current wrap against the screwdriver you don’t have to worry about keeping tension anywhere else like further back on the wire. Splitting the wrap into these two “folds” rather than trying to make a wrap in a single motion lets me be much more deliberate in where I’m wrapping and how close I can get the wrap to the previous one. I most wrap multi-core Aliens than tend to lay down flat as it is, but I use the same techniques wrapping parallel claptons for my series box builds. I usually throw an extra wrap or two into my builds to account for possibly messing up the first or last wrap, so that I can pull Wraps back out if needed. Using a pair of pliers at the end and tightening the entire coil by using brute strength helps too
The last pic only looks like there is spaces because I hadn’t pulled the coil tight...after that last wrap...always have a nice contact coil with no gaps. That’s what works for me, anyway...
