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.
Be Safe When You Cut FRP Grating. These safety tips are very important. When cutting FRP, you should saw a little slower that you would normally cut wood. If you try to cut too fast, the saw blade might get jammed. There will be quite a bit of fiberglass dust, so be sure to use a mask with a proper fiberglass filter. If you donât have a ventilation system, a fan will help direct the dust away from you. You can cut curves and angles in fiberglass grating the same way. You can use a reciprocating saw or a jig-saw. Again, the key is to use a diamond-tip blade. When you cut FRP grating, the general rule is that you have to re-seal it with polyurethane. You can pick up a can of polyurethane spray at any paint store.
