Tutorial - How to make a Cat Whisker for a Crystal Radio

If you ever try to buy a replacement Cat Whisker for a crystal radio, you will find they can be quite expensive. It's super easy to make your own, so in this video we will show you how. it's important to use spring steel as it's designed to be made into a spring. Also be aware it's hardened steel and as such, it should be handled with care. It can break, and it's sharp as a needle when handling it. I'm using 36 gauge but prefer somewhere around 28 gauge, but it still works well. Our next video will include the radio you will see here used in the radio demonstration.
