I decided to LP my Mini 2.1 so I took some pictures for you. I did this on my bench sander with 100 grit sand paper disk and it took all of about 5-10 minutes.

I dismantled the Mini to bare aluminum and gave a wash then plugged the 510 with a piece o gum so I don't any metal in there.

I sanded down the Mini's catch well turning the Mini to each side while sanding to ensure an even square and level result.

The final result with my BF modded Quasar dripper. I sits flush and looks and vapes great.
