I am currently working on building myself a small CNC router, to be able to manufacture my own solid parts designed on my PC. Well, looking around online, there are lots of projects that are great inspiration, but many of these rely on expensive components.
One of the most commonly incorporated parts to be found in these designs are Dremel-brand handheld tools, using router bits, attached to the Z-Axis. Well, I took a look at Dremel tools, at my local hardware store, Wal-Mart store, Target store, and a few other places, but I've found that they're all very expensive, for use in my upcoming project.
Well, I tackled this problem today. I built my "router" on an arm that will be attached to the Z-Axis on my CNC machine. Hopefully, others could use a similar tool, and will find this interesting.
