When my wife and I moved bought our current home about ten years ago it came with an older Woodstock Classic in the lower level of the house.

As you can see the air control consists of the small sliding grate on the side door at the bottom. The cat engagement is controlled by a rod that exits the back of the stove. You push or pull on the rod to slide the cat over the round opening seen in the photo. The previous owner told me he never used the cat and just left it in the position you see in the picture. Once I looked over the stove, which was completely new to me (I had never even heard of soapstone woodstoves back then!), I soon figured out why he didn't use the cat. The top plate was warped from overfiring and the rod was binding.
I took the cat assembly apart, straightened out the rod, cleaned the cat, and got the mechanism working again. Even with the warped top plate I can operate the cat with no problems. This past season, after ten more years of burning, I finally had to replace the cat.
It came with a gasket, but since there is nothing in the design to hold it in place it soon came loose once the tape burned off, so I just removed it since it was apparent it wasn't serving any purpose and would soon be flopping down into the opening causing a problem. The new cat works great and the stove burns so clean that I haven't had to clean my clay tile flue a single time in the past decade. Absolutely no ash or creosote build up!
The only part of the stove that is still damaged is the top plate inside the stove that creates a chamber between the inside of the firebox and the plate the cat assembly is mounted on.
As you can see in the photo the back section has eroded away. This allows flames to more easily reach the top plate where the cat is located and probably contributed to the warping of that plate. My question is: would it make any sense to go to the effort and expense of replacing this plate? As I said earlier, the cat moving mechanism works fine and the cat is obviously working fine based on the way the stove burns and how clean my flue stays. If you do think that eroded plate should be replaced, can anyone tell me how difficult a job it would be to remove and replace and give me an idea of the cost, assuming I do it myself?
