@WhoTookIt: That's really cool, I didn't know these were being sintered now (powdered or sls), and the cross section for HT makes sense. I wonder if HIP would help w them or is it just HT on a sintered ring? I'm not toooo familiar w all the sintering methods but I do have a strong metallurgy background (tool and die and mfg eng) and powdered steel is my wheelhouse so this interesting. I'd think a hardened steel ring, broached or edm cut and turned would also be a good choice or is sintering just a lot more cost effective for the volume? I'm not familiar w the scale of production. In my instance, we have 2-3 shipsets of product and 1-2 test pcs. They would send them back to labs to check for microscopy etc and were trying to chase down the culprit and iirc, nothing is ever perfect, thus we had load into the axis and that would be picked up by the acoustic array. This is probably over thinking it, so my statement should probably be a question.

@WhoTookIt: Very cool information. It was 3 edm pawls, with a broached hardened steel ring. We ended up using a novel system long term since any feedback into the axle resulted in "noise" that the array didn't like, and we found one pawl would eventually wear more than the others, causing uneven loading. Maybe if they let it go it would wear in and even out, but they don't like that sort of thing. This kind of made me think of how grouped hub pawls operate, and if the multiple points on a single pawl even work as intended. I assume you guys did a phased design or? I will say it's pretty cool if a threaded insert (I assume locating off a shoulder?) positions better than a press in! is that a result of manufacturing quality or the press fits distorting? Thanks for nerding out with me btw! cheers.

@WhoTookIt: Were those new rings, or worn in? there is little chance the assembly results in perfectly equalized stresses over long terms. it always ends up loading up the axle/bearing. It's the crux of a pawl system. We used pawls on TAHS (towed array handling system) and discovered the results of uneven wear over time. Granted they are huge systems comparatively. EDM cut pawls help, but there are always tolerance allowances in an assembly that result in uneven wear. Maybe these guys just figured treat it as such from the get go and not to work about the tolerancing! Planned for poor manufacturing! haha.

That's in CAD. In reality even grouped pawls aren't all engaged properly due to manufacturing tolerances, wear, etc, and there is almost always one taking up most of the load, with triangulation using the bearing as one of 3 points of support.

@wolftwenty1: okay, random internet nobody.

@wolftwenty1: randoms like Kolb, Helmstreet, Gwin? What a take. More riders, longer tracks.

I find it pretty wild that guys that fast don't make it to the finals now. There really should be 10 more in the finals, imo. Kolb, Pontvianne, etc are all capable of a podium.

@dv8416: It's wild to see isn't it. Such a so called "protected" spot of land just dozed. Thank god we built the DJs where we did to avoid removal, but I can see that being affected soon too with the changes they are making to the don river. I see you're an OG too, so you'd remember the glory days! VOTLR, Chicken run.

@jkertz: Yup. We were told not to build in Crothers woods, a "protected forest" full of garbage waste that we cleared out and beautified. Years later, the entire forest has been clear-cut to make way for a new subway line bridge. Super sad to see, but it opened my eyes to the reality of how the world operates when it comes to forests. Now I just build doubles and gap jumps on sanctioned trails. Good riders love me, bad riders hate me.
