Start by placing a small lead up against the screwdriver. Slowly and tightly a spossible, wrap around 8 to 10 times. Push the coil to tighten the gaps. Snip the wire with a sterile pair of toe nail clippers. That's it. If all you have is a screwdriver, then the screwdriver method will definetely work fine.
The Coil Master 5-in-1 and also called the Coil master V2 includes one base, five top covers and five coiling poles. The size coils that can be built are 1.0, 1.5, 2.0, 2.5 and 3.0mm. To start, choose the coiling pole size that you would like to use. Unscrew the top cap from the base and insert the coiling pole. Cut a piece of wire and insert it through the hole in the cap. Using the screwdriver, loosen the screw to fit your wire size. While holding the wire with your thumb, slide the cap onto the pole and start coiling. Simple as that. The Coilmaster coils were obviously better and tighter wound coils than my screwdriver method. There is a slight learning curve to using the Coilmaster, but it doesn't take long to get adjusted. I like the Coilmaster, but I also like my screwdriver method. Maybe because I'm used to it. Coilmaster also has newer and bigger kits available.
