Messing with a leftover WSM charcoal ring after a CB upgrade, and a couple charcoal grates from a Smokey Joe, I came up with a better basket to use with the Gourmet Grate. My first version was just the ring cut down to the size of the hole in the GG, but this one is better. Now when I lift the ring out after a cook the spent coals come with it, and I can sift it out to capture the usable coals for next time.
I simply squeezed the ring around a pair of SJ charcoal grates, used one bolt to hold the ring together and used a hose clamp to hold the grates in. (because that's what I had on hand. I really need two, but I had another idea I wanted to try first. See my edit below for the latest.)
Fits just right in the hole, and can be lifted in and out easily.
FYI, two standard baskets hold a decent amount of charcoal:
But I can fit all that, plus another full basket in the GGB:
It's not necessary, but doubling up the grates helps when you use lump, or want to extend the cook without all the small stuff falling through the grate too early:
And yes, the CI insert fits like it should. Imagine the searing heat you could generate with this combo!
