i use a cordless dremmel with a small sanding drum attachment on it and sand the black carbon off… works very well
I like the dremmel Idea I could plug my cordless dremmel in right beside the stove!
Instead of cutting a 1/2 inch off the auger end what if one was to trim 1/4" off the tips of the auger at 45 degrees.
Also I thought of purchasing a burn-pot and having a friend who welds, angle the burn-pot plate down away from the auger tube it would involve cutting the front of the burn pot and re-welding the burn plate supports in.
That way pellets would have a natural tendency via gravity to fall away from the auger tube and the burn would be about 1" further away from the auger and tube thus reducing the carbon build up. I bet it would work. I bet one could build in ash channels on each side were ash would be forced off over the edge into the ash pits on each side of the burn pot thus ending the 24 to 36 hour almost mandatory shut down and cleanup of the stove.
One issue could be the reduced air space below the altered new angled burn-pot but I think the new angle and ash being forced by gravity and new pellets pumping into the burn pot would make this a non issue,
OK Who wants to be the Guinea pig on this one! How about that guy in Maine who burns Cherry pits and coal can't remeber his name I called him last year and shot the chit with him for a good hour.
