I use a grill cooking grate that covers the top of my kettle and set the bucket on that.I'm going to have to rework the bucket thing.
I tested it--propped it up by the bolts, with the bolts supported at their ends. I set 15 lbs. of weights inside (approx. the weight of a typical bag of wet grain). The bolts defected quite a bit, due to the thin plastic wall of the bucket. With a bag of hot grain inside the plastic would likely flex even more, perhaps even fail. I don't want this thing collapsing into the kettle.
First, cutting off the top part of the bucket was a mistake--I made it less rigid. I'll probably need to use another bucket--intact, so that it has the reinforced rim. I'll also need to reinforce it around where the bolts attach, with some sheet metal plates on the outside.
So, drilling lots more holes in another bucket. Yay.
