When I did my first own coil build (back in February last year) that video wasn't available yet... only the button trick was (and also of course Squidoode's video tutorial of the staple staggered fused clapton). I did know about someone else on YouTube using mini clothespins in some other type of coil build, but I can't remember who it was or which coil build, and, what I ended up doing instead was I used a 1 inch key ring with small pieces of masking tape attached to it in such a way that the masking tape was acting like a cushion between the key ring and the spaced claptons. The masking tape prevented the key ring from kinking up the spaced claptons, and also it prevented the key ring from wanting to easily slide off of the spaced claptons because it gave the key ring some better grip. One of the first things I bought when I decided to give coil building a try was a roll of masking tape. Masking tape is dirt cheap, yet, depending how you use it, it can be worth its weight in gold.
P.S., you don't even need any nylon tipped pliers because you can just wrap a piece of masking tape about 10 times around each tip of your regular pliers. The masking tape I use is by a brand called
Tesa... it is a little bit more adhesive compared to other brands so IMO it is much easier to work with.
