Tesla Coil Builders

The two cones are connected in the middle such that the entire length is one wire.  There is no tapping point between the two coils.  I had to replace the copper primary due to age and wear but I am keeping the old copper tubing as verification for the coil's age.  This coil was likely built in the early 1900s and is identical in layout to Tesla's patent schematics from the late 1890s.
