" Ever find yourself needing something that just doesn&amp;#039;t exist to complete a project? Maybe a bracket that&amp;#039;s not shaped like anything you can find anywhere? Or maybe a step-up/step-down/step-up connector with oddball inside and outside diameters? Well, here comes the Internet to the rescue. A site called eMachineShop.com has free downloadable computer-aided-design (CAD) software. You can design exactly what you need on-screen, specifiying angles, thicknesses, shapes and materials. The CAD-ware has built-in short-cuts and also prompts you to redesign something just can&amp;#039;t be made. Then when you and the computer are satisfied with your whazzit, submit the order to eMachineShop.com, get a price and the folks there will have one of the dozen or so nonvirtual machine shops contracted with them make your piece and ship it to you. It&amp;#039;s really pretty neat. Problem is, for now, at least, the CAD-ware won&amp;#039;t run on Macintosh computers that aren&amp;#039;t equipped with a PC-emulator.\u2014Don Chaikin "^^<http://www.w3.org/2001/XMLSchema#string>
