I've sharpened many that were a lot worse, I'm talking .040" burr on the bottom of the chainAfter Philbert posted that close up, looks like your chain is shot. Was likely installed too tight or run w/o bar lube, the bottom of the chain is worn. It will not cut straight.
Although it's certainly not optimal for the best performance. I'll be downstairs tonight, maybe I can get some pics and then do some videos with them for comparison, that would be pretty fun. Maybe I can even do some square ground semi chisel safety chain lol.
He should send that chain to @Philbert for the challenge, I know he'd make it cut straight and true.
