How do I loosen my enail coil safely?
You may be wondering how much you can bend your e-nail coil before breaking the sensitive thermocouple sensor which is found within the heating coil. This is actually a layer which is “sandwiched” in the middle, throughout the length of the coil. This means that aggressive bending could crack and separate this component, leading to an “EEEE” error message. This message indicates a failed thermocouple. Take it slow to avoid this. Just bend it slightly and slowly while holding for 5 seconds or so. Do a few cycles of this and notice the small differences each time. It’s also better not to go too fast because it’s easy to get the coil crooked and un-even. If you do small increments it’s easy to correct any over-compensation.
Take care to go slowly, firmly, and evenly using your other hand to keep the coil aligned vertically. Be careful not to bend unevenly, or the coil could become crooked and slightly less efficient at transferring heat. If this happens don’t fret — you can usually just press firmly back the other way and hold for 5 seconds or so to straighten it again. Using this technique I shaved 1-2 mm from the diameter to make an extremely loose coil fit much tighter. I left just a little wiggle room to keep the banger from being crunched as it heats up. It’s important to leave a little room, since quartz can expand faster than the coil resulting in cracking of the quartz.
What tool is best to loosen an enail coil?
The right tool always makes the job that much easier and more successful. After many daunting trials, I have found that a large pair of scissors is actually my favorite tool to loosen or tighten a heat coil. By wedging a closed pair of scissors in the middle of the coil, you can begin to slowly twist and adjust to get the perfect fit that you are looking for. A scissors is my favorite because of the comfortable grips, and also because they have flat, square outer-edges which provide excellent leverage. You can use a scissors or a variety of other hand tools which work almost as well.
In the video below I show how I used to widen the coils with a needle-nose pliers, which is my second favorite tool for the job. The important part is that your tool has a grip for twisting and also has an end that will lever/grip the coil when you twist. I also had good success with an auger/spade bit, which is a drill bit that cuts holes. That tool is not in this video, but if you look it up and you will see what I mean. It has a nice shape to help grip as you are bending.
