About the Lobo CNC Project
The Lobo CNC Project has developed as an offshoot of one of my hobbies - making guitars.  I have worked for many years in machine design and control, and have built or retrofit several milling machines for my own use.  When I started making guitars, did a lot of the work using a benchtop milling machine I had built.  Most of the work, though, (rather than hogging out a bunch of material) was very delicate stuff like inlays and fret slots, or 3D carving where material was removed in very fine passes.  I needed a sizable working volume and a high-speed spindle, but what I didn't need was a huge Bridgeport mill.

About 10 years ago, I had worked on a very low-cost linear rail system that used guide bearings rolling in folded sheet metal channels.  There was zero play in slides, and they were also pretty stiff.  I had some of these still lying around, so I welded up a steel frame and bolted 3 of them together into a milling machine configuration.  I also added a rotozip type tool for a spindle.  This proved to be great for working on guitars.  I have friends who use flat-bed CNC routers for carving electric guitar bodies, but the the flat-bed configuration doesn't have enough Z motion to carve the heel of an acoustic guitar, and clamping and working on small things like nuts, bridges and saddles is very awkward.  The bed-type milling machine configuration is really easy to work with (although long things like necks and fret boards need to be re-positioned).  

I worked on a couple of guitars using this Franken-mill before I decided to incorporate the same design elements into a properly designed machine.  With the rise of the Maker movement, and the proliferation of D.I.Y. CNC routers and 3D printers, it seemed an open source project was the best way to get this machine out into the world.

And about the name.  One of my obsessions with guitars has been to try to make a decent sounding aluminum body acoustic guitar.  I needed a name to carve into the headstock of my guitars, and wanted something relating aluminum.  Les Baux, the town were aluminum ore (bauxite) was discovered, seemed like a good name, but no one knew how to pronounce it.  So I had a little talk about it with my resident K9's (shown here) and the name ended up morphing into Lobo.  How'd that happen?

And about me.  I have a Ph.D. in mechanical engineering and have spent the last 30 years or so working on robotics, factory automation, mechanical design and machine control.  I live in Bellingham, WA.  If you are ever up in this corner of the country and would like to talk guitars, CNC machines, or dogs, drop me a line.
