Whats the best way to get the rest of this old thimble out without busting up the tiles in the chimney? Cold Chisel? I think the thimble was originally 12" and is now about 5" left to break up. Its got some kind of cement around it as well as at the end where it meets the clay tiles.

Do it in stages--try for only the concrete first & then the thimble--If alls you've got is a cold chisel---have at it--go slow & your tile should be fine. Nice old boards on the original house. ;)

House was built in 1900, 5" ship lap, plaster and lathe. It's a fix-r-upper!

You could drill holes in thimble and concrete to make it easier to chisel.

Howdy,

Best way is to get a small angle grinder and a 4" diamond blade .Reach in and cut length wise in the thimble about 1" apart at the top make three long cuts from front to back, strike on middle cut with cold chisel and the two top sections will fall out, make maybe four more cuts and remove. then do the same with the cement as necessary to accommodate new thimble. no worries!

Still have to get some of the old mortar out.. my guess is several hours of work there. then place the new thimble and let the new mortar dry for 24hours. Code enforcement has to come out and check the box, same with home insurance co. Then Light it up!

L, how much space do you have between the end of the thimble & the chimney tile???? Yep, get that all filled in/pretty'd up before anybody looks at it ;)

I know this is only my thoughts, but, if you've got 8" tile--or even 6" I would cut that thimble so it only goes into the near side of the clay tile an inch or a little more. It will give you a lot better draw.

take some rich stiff mortar almost like putty reach ur hand in there and pack it full of mortar at the joint of the thimble and the flue liner...refractory cement would be great as it will withstand the heat better reaching in there 12 inches is for sure a hand job...tools just wont git it packed in very good...
