That's where my worry comes in. I'm worried I won't be able to do it. I'm also not very savvy with DIY things. Every time I try, it turns out like something a 3 year old did. Lol. I just do not want to have to go purchase pre-built coils because I can't get mine to turn out right, meanwhile my wire and cotton is sitting in a drawer never to be used again. I guess I won't know until I try. Lol
Nothing difficult about wrapping a piece of wire around a drillbit. Start with a piece of wire about 6" long so you can handle it easily, have something to grab onto while you're mounting it. Also, run some kind of flame over the wire before you wrap it -- but not enough to melt the wire, just to make it less "sproingy". I just use a Bic lighter, though there are all kinds of 'spensive torches for that purpose. Try to put each wrap as close to the last one as you can, without overlapping -- it doesn't have to be perfect, because you can still get it tighter, once you mount it.
Once you get it mounted, you can dry-burn in order to squeeze it more tightly, if you want to, but NEVER EVER touch anything metal to the coil while you're pressing the fire button. Once your finger is off the button, while it's still very warm, you can squeeze it with tweezers or needle-nose pliers, but don't get carried away, it's kinda soft right after firing.
