I've been making my coils on a 2/56 machine screw (makes a perfect coil) 6 wraps give me 2.4 - 2.5 ohms and 5 wraps give me about 1.8 ohms. Up until now, I've been successfully wicking by pulling one doubled over piece of 1mm silica wicks thru the coils. Here's my problem and question if anybody can help: just purchased a quantity of 2.5mm silica rope wick and I'm stumped about how to get a single 2.5mm silica wick thru those coils! Does anybody have any suggestions? I prefer not to make my coils larger diameter if I can avoid it. I really like the wrap diameter on the 2/56 machine screw.
