Hand made carbon fiber violin is a stunning work of craftsmanship

Building a violin by hand is no easy task, but constructing one out of carbon fiber is an amazing feat! Carpenter [Ken] had never made a violin before, nor built anything substantial out of carbon fiber, and he figured the best way to learn was by doing.

He spent a good bit of time measuring and drawing out his design before making fiberglass molds of the violin’s front and back plates from carved plaster plugs. The process was extremely time consuming, requiring him to make 10 different infusion-molded carbon fiber body plates before he was satisfied with the sound they produced.

With the larger parts of the violin’s body built, he started on the rib molds, which took him 5 hours apiece to set up before injecting the resin. With the body complete, [Ken] was ready to cut the f holes into the violin – a process that required a lot of time hunched over a tank of water with Dremel in hand.

As you can see in the picture above, the final result is stunning – we just wish we could give it a listen to see if it sounds as good as it looks.

Building a robot without using a machine shop

We usually avoid the prospect of buying new tools just for one project. In the long run we’re sure we’d use them again, but sometimes even with that outlook you can’t afford it. Case in point is our life-long-lust for a laser cutter; we just can’t justify the upfront cost but we sure would use it constantly if we had one.

If you do find that you’re interested in taking on a project that calls for laser cut parts, [I Heart Robotics] shows you how to do it with a few simple hand tools. The bot seen above is their TurtleBot. You can cut your own parts using a laser cutter, you can buy a kit from them, or you can bust out a ruler, compass, drill, coping saw, printer, and tape to make the pieces by hand.

It’s a simple enough concept. Print out the templates, tape them to your hard board, then start drilling and sawing. You won’t get the precision a machine tool can, but in some cases you don’t need to be all that perfect.
