Nikola Tesla in his 60s adjusting a radio device in his lab in New York City. Like most significant inventions, radio had not just one âfather,â but many. British mathematician James Clerk Maxwell first proved the existence of radio waves mathematically in 1864.
Cutting with Rotary Tools. Rotary tools are the most widely used method for cutting composite laminates. Whether you are cutting carbon fiber sheet or a fiberglass hull, there is usually a rotary tool just right for the job. Rotary cutting tools vary from small handheld rotary tools, like a Dremel or pneumatic rotary, to routers and even angle grinders.
The speed and quality of the cut depends on the condition of the saw blade. Never cut with a dull, rusty, or damaged blade. I recommend using a thin-kerf carbide-tipped combination blade, which can be used for crosscuts and rip cuts in solid wood and plywood. With the saw unplugged or the battery removed, adjust the saw's depth of cut so the blade extends no more than 1/4 in. past the board's edge.
