Long time troller here, and I was hoping someone could help me with a small issue I am having with my Char Griller with SFB. My setup is pushing 5 years old, with no mods done. It has been incredibly faithful and I have never had a problem regulating or distributing heat till recently. The metal in the SFB ash tray has started to warp from the heat, and no long closes completely. Now I can't control the heat because to much air is getting in. I was wondering if anybody else has had this issue and what they have done to fix it. I didn't know if there is a way to close the gap (1/3" at one place) or a work around to get the tray to close completely, or to replace the tray. Thanks in advance for your advice.
