With my recent dive into making my own coils one problem I have ran into is that while I am wrapping the coil around the silica, as instructed in many videos, it starts to rip at the start of the coil, where I am holding the silica. Is this normal? Anyway around this? I would love to wrap the coil and then feed the silica through the finished coil much like cotton is used but have had no luck with that.
