I have many other projects in mind, some of them requiring a larger machine than mandolin would.Īnyway, your opinions will be appreciated as well as some ideas on how best to attain the accuracy needed. After fiddling around with different ways to construct things it seems I may have to just make a smaller machine than I wanted since size is somewhat less important than accuracy (to a certain point). But when I run my ideas through their Deflection Calculator program I can see that they flex more than I would have guessed. that would be required to build a good sounding hollow body instrument, such as a guitar, or mandolin.įor instance, how many thousandths of an inch is it ok for the table to sag under the weight of things while cutting? My first inclination is to use 80/20 extrusions for framing. Before I get way ahead of myself in design I would like to hear some opinions about the minimum accuracy, etc. I am going to build a CNC in the near future. ![]()
