For me its the old fans and vacuum cleaners. Over 40/years old each and still going strong. Clear labeling inside and have been fixed up multiple times.

        I have a round griddle that was warped enough it was almost un-usable on my glass top stove. Here’s what I did.

        Using a ruler and an angle grinder, I knocked down the high spots. When I put it on the stove again it was significantly better but still a bit wobbly so I took a cheap 2-sided sharpening stone and continued taking it down with that. It took a few hours to get as flat as I wanted but, I felt like it was worth it.

        This has three methods: sanding, hammering, heating with weights. (not linking because I have no idea if the site is slop)
