Yeah the hammer whack was mentioned (not by me) as a way to tighten up Mafacs. Hopefully no one would do that to a Weinmann, since it wouldn't help on those.

I know some people dis the Weinmann design, but I think it's brilliant, especially from a manufacturing point of view, so easy to make and at the same time so effective at doing the job they were made for. They're tough too, able to withstand a decent amount of crashing and other abuse. There's a reason they were on 18 bazillion bikes, especially if you throw in all the knockoffs from DiaCompe, Cherry, Chang-star and who knows how many others. But the bazillions of them might make modern riders forget they were also the best, until Campy arguably made a better mousetrap. Even at the very high end, Spence Wolf liked them, as did Rene Herse. Plenty of pros won races with them.
