Yep, I learned from Alton Brown when he was doing his Chimney Tuna Loin but I have since adapted it filet mignon, thick chops and turkey loin, among others. Works great even in winter temps over wood chunk for great smoke flavor.
Best way I have found to rig it is on my Weber One-Touch kettle:
1. Remove kettle/grill grate and set chimney on bottom coals grate.
2. Fill & light chimney as normally directed.
3. When coals blazing at "jet engine" level where the top layer is almost completely white, place the grill grate on top of chimney to heat up.
4. After a few minutes place your meat of choice on grate directly over inferno and sear to your liking.
5. To finish using indirect heat, carefully move meat to edge of grate not directly over inferno and cover with smaller dome lid with vents half-open. I use the lid from my ECB or Smokey Joe lil'
Weber kettle. ***Be very careful when moving the meats and placing/removing the lid as the large grate needs to balance properly on the chimney.
Sorry I don't have pics handy to show you but PM me if you have any additional questions.
