Cut your copper. Here we did four short sections (legs) at 6", and two long pieces at 12". The important thing here is, again, to size the height of the thing to your mugs. We ended up making ours a little too tall, so when the coffee drips down, it splashes a little much. Fortunately, the copper legs are easy to shorten, so after we photographed it, we cut them down a few inches so the dripper sits closer to the top of the cups, diminishing the splashing.
So, when sizing your parts, I'd say go for about two inches of clearance above your cups.
Clean all the ends of your copper pipe with sandpaper or a pipe cleaning tool (below). If you were using these for actual plumbing, this step would be more important, but since these pipes won't be functional, it's just about roughing them up a bit to help strengthen the joint.
Solder the pieces together. Make sure to use proper safety equipment and do this in a well-ventilated area (a garage or even outside). The solder will smoke a bit and you don't want to set off any fire alarms.
Drill a hole to insert the brass collars, the same size as they're outer diameter. (Ours were 3/4".) You can measure the positions, but the copper is a little forgiving, even when it's all soldered up, so you have a little bit of play. I just eyeballed it and marked the spots with a marker.
Lastly, slide the copper structure onto the collars, and put the kettle on.
Now brew some delicious coffee!
