thanks for playing.
of COURSE I make a comment based on what I've seen and I get a certified machinist, ok you win. (and why aren't YOU making track ends? )

so your saying the bottom edge of a waterjet cut is kerf'd? (yes I know what a kerf is) and wavy? I never saw that on parts we did, but then we never really cut anything thicker than 0.500 (I work as a fabricator)

and isn't +/-0.005 kinda close tolerance for a dropout? (fork end)? human hair=0.004

not trying to be a smart ass, you obviously know way more than me, just trying to confirm what you said.

(oh and I still want a pair of the track ends )
