Cool! I have 2 grates in this and want to use for grill or smoker. Using the bottom of a kettle is a great idea! You can use many different hinges. I chose to use a big t-hinge and use it verticle. The triangle side goes on the lid, the rectangle section on the body...right at the cut. Seems to hold up well. some dont use hinges and just lift off the lid, but I like the hinge and chain much better.
