I've been looking for a new stove for a bit, but due to lack of dealer supply in my area, and major indecision on my part, I'm burning the Harman tl200 with not much of an afterburner left, so.....it's basically a single burn stove with internal damper. (Yes, I'll be cleaning the chimney more often). I've begun to re-gasket to get me through the winter and tighten things up, but I've got one that's just plain not sticking. (It's the damper weldment, kind of an important gasket!) I'm thinking a dremel with an abrasive bit, down to bare metal. Never had a gasket that wouldn't stick at all. Any tips?
