Simple tool to aid copper clad circuit building:
For ham radio enthusiasts the art of building free-formed circuits using little bits of copper clad board is second nature. But [AndyDaviesByTheSea] figured out how to build your own tool to make the process much easier.
First, here’s a quick rundown of the traditional build method. One base sheet of copper clad serves as the ground plane. Small squares of copper clad are cut and super glued to the base sheet to serve as the signal pads.
[Andy's] variation on this is to use a hollow drill bit to isolate small circles within the ground plane. You can see above that this gives him signal pads that he doesn’t need to glue on. He made his own tool to use in the drill press. It’s just a bit of tubing into which he cut several teeth using a hand file. Check out the step-by-step video after the break to see how it’s done.
