I have a big heavy cast wrench that says "Euroline" on it. I think it was $30. Looks like this picture I stole from here
Inmate Donkey Hotey made fun of me for lugging it around.
So, I CNC'ed a nice compact one, better than the Ed Korn one shown in that link since it extends to both sides of the ratchet axis.
Speaking of ebay, I just scored some cheap new /2 parts from someone who said they got the inventory of a closed BMW shop. I'll try to find a link.
