I've found the articles/instructions on how to make a plastic cowl from a soda bottle and a foam plug, but I've only seen one picture of a cowl that has been made that way. Does anybody out there have any examples of cowls they've made from plastic soda bottles? I know it would not be very complicated to make one from fiberglass, but I'm looking for the easiest way because it's just for an Avistar that I'm using for aerial video....the front bushing on the engine is throwing a good bit of fuel/oil, which ends up covering my camera lens. I think I can make a cowl to help contain all of the oil and keep it away from the camera. I was just curious how other folks' projects turned out.
