For this you will need the entire contents of BAG 2 plus the M5 nuts and bolts from BAG 1 and copper wire.

Assembling the coil former:

You will need one 0.8mm coil top either brown or white, one 1.5mm thick spacer, one 1.5mm base and one 1.5mm thick terminal holder:

Clean up any loose material using sandpaper or a knife.


Assemble the pieces onto one of the M5 bolts in this order then run a couple of drops of superglue into the groove and round the edge of the terminal holder to hold the pieces together:


Thread the copper wire through one of the terminal holder holes and wrap enough around the bolt to hold it in place:


Wind 55 turns around the spacer in the groove formed between the coil ends as you did with the display piece coils, cut leaving a couple of inches of wire and feed this end through the other terminal holder hole. If you find the resulting display a little dim reduce to 54. (Try a couple before winding the whole batch)

Varnish or glue the windings in place. Once the glue has dried remove the bolt.

Repeat this another 64 times.
