My 3D printed antenna is extremely fragile, so I decided to try making one out of brass tubing and washers. It worked much better than I was expecting! The process was pretty simple, mostly just soldering and sanding/polishing.
The hardest part was drilling the ID of the washers to the correct size. I ended up soldering a stack of washers together (super glue wasn't strong enough), placing the stack inside the drill press chuck, and very slowly bringing the chuck down over a stationary drill bit. Once the ID was correct, I melted the solder and separated them.
Many washers died to bring us this information.
