I cut out some templates of the grills to make some drag grills. My bro-inlaw makes signs out of corrugated plastic and will make the grill covers and put in some grommets that I plan to use toggle bolts to attach to the grills. Do ya'll think these will work, or is it a waste of time and material? My other bro-inlaw works for a sign company that makes signs for fast food joints, the ones up on the poles, and could maybe get him to make them, but he would have to charge me and I'm a cheap bastige.
