I have built a few coils on this kayfun and it is always a hassle trying to get the wire to screw down. The wire always slips out and doesn't tighten down. I have had to loop the wire all the way around the screws sometimes just to get it to work. I have been trying to get a new coil on for 45 min and I am about the throw it out the ....ing window. This kayfun has the holes under the screws also. Is there a certain way I need to do the coil to use the holes under the screws instead of wrapping the wire around the screws? Any suggestions about the wire slipping out? thanks
