So, I picked this old 18" Bar-b-kettle out of a neighbor's trash last Fall. Finally had a chance to clean it up today. Replaced the dampers and got some nice wood handles from Etsy. Went to put in a hinged 18" grate I bought a while back for my Jumbo Joe and found that it slid right past the grate ring on the Bar-b-kettle. This doesn't have brackets to hold the grate, just an indent around the circumference of the bowl that it rests on. The original grate is still in there, bit super rusty, so I'd like to replace it. The JJ grates measure 17-1/2". This one measures about 17-3/4" or 17-7/8". Maybe the top grate from the 18" WSM would work? Anyone have one they could measure for me?
