Ashful
Minister of Fire
I have a 4" round cast iron drain grate that is a perfect fit into the hole left by the 4" square ash plug in the Ashford 30's, which is the same thickness as the upper rim of the plug, such that the top of it sits flush with the brick when installed.This shagbark hickory is something else. I have about a cord at least to go. If there was a ash vac that could take everything out of the king in one shot hot coals and all I’d buy one. Even if it was a grand. That fine dust is like sanding Sheetrock.
In any case, I pull be plug, use the same tool to drop this grate in place, and then use an ash rake to plow the mix of ashes and coals across the grate. Ash falls thru, coals stay in the firebox, voila. I don't know how anyone manages to use an ash plug system without some type of grate over the hole, and think stove manufacturers using an ash plug system should just provide this as part of the rig.
No need to ever get a stove perfectly clean, other than occasional inspection. I just scrape the ash thru the hole, and don't bother with a vacuum other than August/September, when I replace any damaged bricks before the new season.
