I'm preparing to reline an existing clay lined chimney with a 6" stainless steel liner. I currently have an 8" diameter steel thimble that has been mortared in. The depth of the existing thimble is about 22". I'm planning to get a tee connector with a long snout. I'm unsure of the best way to fasten the new snout in the thimble and make it sturdy, look nice & easy to access for cleaning.
Thanks for your help
