[Rapid Vanguard] Tesla Spikes These parts will be used to make the coil for each spike. Slot the 2 parts from the previous step together to make a coil. Set aside these parts in this order. Take the parts from the previous step and slot them down over the long peg at the bottom of the coil starting with the smallest and going to the biggest. There are only 3 types, but you will use 1 small discs, 2 medium discs and 2 large slotted discs. Slot the whole thing into the base plate. If any of the tab protrudes from the bottom, sand or cut it away. Gather 6 fins as shown above. Insert fins into the slots around the bottom of the coil. Glue the acrylic sphere into the top of the coil and the Tesla spike is complete.
