Pop off the top cap. It is just pressure fitted. I wrap a coil around a 4 mm screw driver with one lead down and one lead going up the screwdriver. Cut a piece of cotton pad and wrap around coil and slide it in. I use a opened up paper clip to poke it down into place with the screw driver still threw everything. With wire up at the top, the cap has a groove and that is where the wire goes threw. Tap the top back on . then I put the screw driver back threw and put in insulator with wire threw the middle then install pin. Then I normally pop out the pin carefully and clip the wire and reinstall the pin. I do it that way as it pushes the wire to the side of the insulator and I can then clip the wire shorter so it does not ground out when you screw it into base. CHEERS!You got a tutorial video on rebuilding the regular vertical heads that you'd like to share perhaps? Or... Maybe just some random tips and tricks as they pertain to these coils and rebuilding them? Thanks, Dave

Take out the spaces.
Also I build new coils but video will give you the idea. I do not take off the o ring like the video does.
