Thanks you, I knew you guys would appreciate it.
These are really easy to make all you need is some cardboard, packing knife and some $$$
I start by tracing the curve of the charcoal grate onto some cardboard, you want to make it about an inch longer than the actual grate as the tray will be longer than the charcoal grate due to the shape of the bowl.
Then fit the cardboard in the bowl on top of the charcoal grate and trim till your happy with the fit.
Set the charcoal baskets up in the kettle on top of the cardboard and mark where they fit.
Trim the cardboard to fit the baskets until your happy with the fit. This should only take about 10mins
I then take the template to a fabricator/welder and get them to make it.
The sides only need to be an inch high for a 22 kettle
Just make sure you cover in foil when cooking it makes an easy cleanup when your finished
