Are you saying that it would be best if possible to have the thimble inserted into the chimney liner an inch or so? I think that in order to do that I'd have to chisel away some of the clay tile and hope it doesn't break
Its a tight fit currently (not very straight either). At the local brick yard, Frederick Block here in Winchester, VA they have 6 inch diameter thimbles in 12 or 24 inch lengths only. I wonder if I should have bought the 24 inch and have the thimble stick out of the wall more. From the chimney its, liner - > cinder block -> ship lap wood siding -> lathe and plaster.
