Simple, grab pliers, twist wing nut with them till the tac welds break (you'll hear a pop) and spin off wing nut, out comes wheel assembly.
I've done it to several already. No need to drill the welds off, they are pretty crappy welds to start with and I found it way easier just to snap the little welds by forcing the wing nut off.
Took all of 2 mins.
Just make SURE to pin drum to 5
