Well I did it. Here is the attachment complete. There are large nuts between the drum and the Weber kettle section to prevent twisting the kettle. there was a 1/4" gap I need to fill. here is the gasket stuffed in the gap. I have Hi-Temp RTV, Red. Will wait and get something in black. For those really tall smokes. The rotisserie ring. The mod went well and the kettle stayed round and level. We will see this weekend, I'll be doing a pork shoulder if things go as planned.
