Rocking Chair for two

I’m sure a rocking chair is not what you’d expect to see from a technology program. But Chairish, Annelie Berner’s rocking chair for two is the work product for a class called Design for Digital Fabrication. Using CAD software, Annelie went through many design and prototyping iterations. Eventually, she cut the design out of plywood with a computer-controlled (CNC) router. The pieces are held together with threaded rod and nuts to make a chair for sharing.

A custom designed lithopane lamp with a rotating shade

The project I would like to share is a custom designed lithopane lamp with a rotating shade.  To keep within the Instructables spirit, this is a project that anyone with basic wood shop tools such as: a table saw, scroll saw, router, and some basic hand tools, can complete the project.  I took it a step further to show how cool a CNC router can be – and I don’t have a CNC router with near the same capabilities as a ShopBot.  My router is at best a worn out, low tolerance, entry level router with a 12” x 18” table, a Rotozip for a spindle, and powered by a HobbyCNC controller.  The software I use is borrowed from my work (after hours of course) and is SolidWorks for design and BobCAD-CAM for the CAM which we use for networking product design and manufacturing assembly fixtures.  I am not in the wood industry but do like wood working as a hobby. Should I be fortunate enough to win the ShopBot and AutoCAD software, I would like to design and build larger woodworking pieces such as kinetic sculptures and clocks - mostly moving wooden assemblies.

Cup Holders

Cup holders from Advanced Wood Production Class. Both pieces were cut by a CNC Router from a 2'x 4' piece of wood and fit together without any glue or fasteners. The cup holders are designed to easily fit a beer bottle, those red plastic cups or  glasses.

Technology challenges the master violinmaker

Most people consider Italian violinmaker Antonio Stradivari the greatest violinmaker of all time. He’s getting some competition from technology. Today, on Engineering Works!.

A team of modern violinmakers and a doctor is using technology the 18^th-century luthier never dreamed of to measure and duplicate – almost exactly – violins built by the master.

The doctor, a radiologist, or specialist in medical imaging, also is an amateur violinist. He came up the idea of using computed tomography, or CT, imaging to get exact three-D images of one of the 500 or so Stradivari violins that have survived to today. The CT scan produced more than 1,000 images of the 300-year-old violin.

Then they converted the CT images to computer files that programmed a computer numerically controlled, or CNC, router. The

CNC router is a machine tool that can shape new violin parts to almost exactly the dimensions of the originals. The scans also show the density of the wood in individual parts. This allows modern violin makers to use different woods to match the density of the original. The newly made parts seem to match the originals.

One of the best things about this approach is that the original instruments aren’t disassembled or damaged. The researchers say the imaging is so detailed that it could also be used to identify individual instruments and track repairs to them over the years since Stradivari made them.
