Hi, my name is Ted Webb and a â€˜new guyâ€™ on the forum! I am a retired avionics engineer involved with the F-111 (aircraft) Terrain Following Radar (TFR) for many years. The F-111 went the way of the buggy whip and so did my career. Canâ€™t complain though, it was a great ride! I was raised in Ft Worth Texas and employed by Texas Instruments/Raytheon for most of my career. Late in my career I worked for Boeing Australia. I came to Australia in 1995 to provide technical support for the F-111 TFR until it was withdrawn from service here (in Australia) around 2011. At that time I officially retired. We live on a small farm in Southeast Queensland about 12 miles from the nearest loaf of bread. Even though my career was in avionics, I have always been interested in â€˜mechanical thingsâ€™ and have often quipped â€œIâ€™m just a frustrated mechanical engineerâ€. I have no mechanical engineering training, but on the farm I often find â€˜problemsâ€™ which I think has a â€˜mechanical solutionâ€™. I lack the mechanical engineering skill set to develop those solutions! But, Iâ€™m anxious to learn! Iâ€™m a â€˜Jack of some trades, master of noneâ€™ type guy. I have experience in robotics, welding/fabrication, machining, CAD, small engine repair and whatever it takes to keep the farm running! My two current projects are modifying an old ride on lawn mower to a â€˜fence mowerâ€™ (to mow under the bottom strand of a barb-wire fence) and build a belt driven trommel to tumble dry horse pee soaked saw dust. I will definitely be using the forum to gain insight in belt drive design!!
