Wire brush bristles can come off, stick to a grill, transfer to your steak, and best case scenario stab you in the mouth… Ask me how I know. Worst case you intestine.
Stick to the biodegradable fibre ones, or this seems like and ok option.
But for the love of god, do not use a wire brush.
The previous user had printed some plastic plates to attach the front and back. However because I stacked it 20+40 top and 40+20 bottom, screwing them together also helped hold everything.
NGL, it was a fair amount of work, but way less printing and no custom glass/plexi. It’s probably a bit more expensive, but not prohibitively.
However, I’m very confident this is way sturdier, better sealed and much quieter. Will be more so of all when I add one last set of connections in the bottom and the sound dampening up top.
I love how you offset the 20/40 frames, much better than my design
