The cones look good. I must be cheap, though. I used .090 in. weed eater line and put a 3 in piece every 2 in. into, it looks like the same plastic pan. Take a lighter and melt the end of a 3-1/2 in. piece of weed eater line, press it flat ,push it through bottom of pan. when all are in place, take 15 min. epoxy and secure them to the pan from both sides. A one dollar pan several years ago and still going, going, going.
If at first you don't suceed, go fishing, then try,try again.
