    Rotary broaching. It's tough to explain easily in words, but there's a bunch of videos on the web.

    That is the single most nifty bit of tooling I have ever seen.

    Just had a look at that, amazing stuff. How good are the tolerances? In the Slater Tools vid I was watching, there is visible deflection of the tool when it begins cutting.

    Haha I watched the same vid. I think what your seeing is the beginning of the wobble no?

    I don't know about the repeat accuracy if you're producing a few hundred parts. But last Time I used this Tool on the CNC Lathe I did five parts and they stayed in a range of about .05 mm.

    The tolerances on the parts I had made are tight- the 8mm hex key fits pretty much perfect.

    Pretty good. The deflection or wobble of the tool is needed for it to cut the material (usually there is a 1 degree wobble).

    They might be moving together. It seems that the CTA holds them together permanently. The wording of the rigidity claim is very smart. They only say that it is 50% stiffer compared to the equivalent Emerald w/o the CTA. I wonder how it compares to the competition.

    Doubtful even without the CTA that it is less stiff than the dorado. Granted the dorado has the hexlock, but its decreased stiffness in relation to non-inverted forks has not been a detriment that i can tell while riding/racing

    I love the Halson reference in the PB article...but does he remember the PBF too?





    As for the devo, still lots of plastic bits on the prototype...will be interesting to see the actual finished product. At least they got their anodizer sorted! Not sure why you'd go with a coil negative spring on an air fork...RS have a patent on dual/solo air?

    double edit:
    DVO has gone to great lengths to create a piston that permits a lot of oil flow via smooth, open porting. This lets them control the fork's damping characteristics with MOAR shims than would otherwise be required of a lower-flow piston, the advantage of this being a large degree of tuning by way of using MOAR and different shims
    The only important part for any RM user.
