Early in the process. Throw back.
38mm? What size do you think they are now.
They look good.
Is it consistent all the way around the chip? Looks like it would be hard to get near perfect.
well TRK's are a bit smaller from manufacture, not much, Ill get the micrometer out, but I'm not taking a full mm off in my process. The machine we made insures they stay round so there is no chance of oblonging the chips at all. They stand and roll perfectly after treatment.
Other suggestions I read in other threads mention heating and flattening chips to keep them at 39mm after treatment, but honestly I believe that's a terrible trade off. You hardly notice the difference between 39mm and 38.25 (On the really bad chips). Deep flea bites have to stay in the chips too because you don't want to treat them down to far. A sharp edge with a nick is better than 37.? chips!!! lol
Face shaving is NEVER an option for me. I wont thin a chip, shit some bike tires are thin enough!!
My process works best with chips that will either stand on edge but look shitty or will "almost" stand on edge.
This weekend I'll post some pics of the next experiment edging some real thin chips.. Not sure that's worth the effort but I have to see it for myself!
I'm thinking that a 2 fold grading system may be the deciding factor on expected results:
1-4 on edges
1-4 on thickness
