The grill-retaining rings are proving to be a PITA to extract...I can't brute-force it either because the cups are wood. Ughhhh.
Edit: it's coming out...Ah ok so these don't have the 4 plastic tabs and slots, instead it's only held down by the glue. I guess that makes sense with the wooden cup.
Interesting, but that does make sense. How do you think that will affect doing the grill mod? Seems like a PITA to have to glue them every time. There should be some substance that will make removing the rings easier... putty or tape.
