It's a difficult build the first few times, not recommended for beginners, the frustration curve would be too high
But if you are daring and handy, its an amazing build. It's a smaller gauge wrapped around a straight piece of larger gauge. For the sub tanks 32 gauge around 28 gauge works great.
For you to start, I would suggest a simple macro coil using 26 gauge... Something like 6 wraps on a 3mm ID (larger id's will wick a bit better). The trickiest part on the will be the wicking.... We have learned that the less is more theory doesn't work well on the sub tank. Pack the coil fairly tight, then thin out the tails a bit.
As far as the Clapton, there are some good tutorial videos on YouTube, just search Clapton coil
