I've wanted a square griddle for bacon. I have also wanted to try grinding one down like the old stuff. I used an angle grinder with flap wheel and dremel with sanding drums for the corners. Then smoothed out with an oscillating tool with triangle sanding atttachment. Seasoned with refined avocado oil ramping up to just under 500deg over an hour.


I might try smoothing out my other skillets. Round ones should be easier to get nice n flat with a random orbital sander. Just might take longer.
