|The broken Park Tool chain tool with the broken piece in the center|
That surprised me. Overall this thing is built very stoutly. Those steel outer shells seem much stronger than they might need to be, for example. You could bang on them with a hammer and nothing would happen. But that little chain horn, it snapped right off. I'm sure there are one or two guarantees or warranties I could take advantage of in response, but honestly, it's not really worth the time it would take to pack it up and ship it somewhere. A) I have another chain tool and B) I definitely don't want another one with horns like this one. Even if you're not supposed to put the chain over the left one to press out rivets. You're also not supposed to bang on those outer shells pieces with a hammer, either, but you could. If/when I buy another one, I'm looking for a design without little fragile horns that break off, even if you line up the chain wrong or try to use it on one rather than the other.
Events like this call the whole enterprise into question, though. If the engineers behind this tool, who must have decades of practical tool engineering added up to make this design, still turn out something that does this, when faced with real world forces and usage, what chance does any of us have when facing the same types of dynamics in our own day-to-day activities?
This was a systematic fault, where the system consisted of this tool, my hands, the chain mounted on the horn of the tool, and the torque I was exerting on the handle converted into linear pressure against the pin which transferred to the base of the horn and snapped it off. By extension, I suppose, to the makers of the chain, the makers of the tool, the designer(s) of the tool, the steel mill, the miners who dug the ore, the sailors who carried the ore in the ship, the coal miners who mined the coal that made the coke used to make the steel, on and on, all of us in a related system, my muscle power (very little of it, in fact) turning the handle and disappointingly snapping off the horn. The locus of the fault was the base of the horn, the right angle corner where it joined the body, but the factors which met in that moment to press the fault from latency to actuality were vast.
This is one reason why I resist simplistic, scapegoaty answers when stuff like this happens. All those things, all those connected, related, and distant factors, don't convert from latent fault to actual fault on 18 Oct 2015 except by my agency in making it so. Perhaps another time, another place, another person, another chain, also this horn would snap off, but who knows the odds of those potential, non-factual non-actuals?
This one, I just learn from. No more chain tools for me like this one, no more snapping off this type of horn in this type of operation for this or similar reasons. A better, a stronger, a stouter, a different design, will all be in my future chain tool plus chain plus torque systematic meetings. I blame no one for this but me. I want nothing else from this experience but experience. Data to learn from. Future chain horn snappings to avoid, by me, with my particular, peculiar, but my own, combination of movement, force, agency. I don't plan to break any more of these, not like this.
|I always carry the old ones, which I noticed are now marked "8SPD" which helps. E2 vs. C2 I need to learn.|
