It occurs to me that the axle nut is the single most important component preventing the axle from spinning in the dropout. The axle nut is threaded onto the axle, and if properly tightened with a locking washer (or other mechanism) compressing it to keep it locked on, it effectively becomes part of the axle itself. And if it's clamped onto a solid flat surface that's part of the bike, then the axle can't spin. From what I've read online, clamping force is extremely good at resisting shearing.
Common wisdom here seems to suggest the torque arm mainly needs to squeeze the two flats of the axle. But it's well known that solid steel dropouts, that do just that, can be ripped apart if the axle nut isn't tight, suggesting they really don't do much at all.
I'm lazy and it seems like the easiest method to make a torque arm, which should be very effective, is to make a steel arm that grabs the swingarm, with the other end wrapping around the axle, but not necessarily the flats. You can have a 14mm round hole there, and if the axle nut is clamped very tightly against it, surely this would be a perfectly good torque arm? I'm considering doing just that, probably with red Loctite (vibration-resistant, requires a heat gun to remove, which I have) for good measure.
We have tons of electrical engineers but are there any mechanical engineers here?
