I am going to be smoking 18.77 lbs of pork shoulder and 9.36 lbs of chicken for a potuck at work. I made a USD a couple of weeks ago and I use the cooking grate off of the Weber 22.5" kettle. I am a little worried about the weight limit of the grate and I was wondering if anybody else has made that much or knows if the grate will hold the weight. I use three bolts to hold the grate at the top of the drum. Thanks.
