Ham Radio Coil

While shopping in an old electronics store shortly before it closed down, I found an interesting old ham radio coil that was missing a few parts. I bought it and decided that I would use what was left of the device as a pattern and recreate it. I tried making a mold of the insulators from latex unsuccessfully, and ultimately poured the mold using silicone. I cast the insulators from resin, and cut the support rings from a PVC pipe using a miter saw. Instead of the original’s steel band coil, I opted for a┬ábrass coil of the same parameters.
