When learning to build remember Keep It Simple. I'll go over the 4 basic builds.
nano, micro, macro coils. This is just a single wire wrapped around a spindle. The difference is the size of the spindle.
Nano < 1.5mm, micro >1.5mm but <2.25mm, Macro => 2.25. These are the most basic and easiest coils to build
Coil size is stated as mm ID. (mm Inner Diameter)
Next is twisted, parallel, kissing parallel. Simply put these are 2 coils on one spindle. So 2 (or more) wires twisted together, coiled side by side untwisted or Kissing *2 coils mounted on one side as -/+ and +/-. Advantage is lower resistance and shorter ramp up. For example.. 4+4 wraps (2 coils) is lower resistance and ramps up faster than 1 8wrap coil. Kissing means 2 coils on one side meet in the middle to form 1 coil. They can also be used separated for a quad coil build. For now, concentrate on twisted and parallel. Kissing and quads will come shortly after a couple builds.
Clapton is a core wire such as in the macro coils wrapped with a high ga wire 32ga or higher so it resembles a guitar string. Hence the name Clapton. When starting to wrap clapton coils, do one at a time. Much easier to control 8 inches of wire than 16 inches.
Finally Fused Claptons. Exactly like the Clapton above except you use 2 or more wires as in parallel coils. Again, start by making 1 coil at a time for control while learning.

Once you master these you can configure your core and wrapping wires in very complex coil builds.. such as 3x 26ga + 2x flat ribbon wire, fused *claptoned together*. Or 5x flat ribbon wire boardered with 2x 26ga wire and fused. *claptoned* together.
Im lazy so I ordered a deadalus coil jig *with drill* for more complex builds. It automatically wraps the core wires with the fusing *claptoning* or wrapping wire. It is a bit pricey around $60 but when you consider some coils run for $5 to $15 and up each..it pays for itself quickly.
Note.. I highly do not recommend the Deadalus coil jig kit without the table top drill. You technically can use your own hand drill.. but the jig tends to vibrate and double back past a certain speed and is a pain in the ass to hold while wrapping your coil.
