If these weren't vintage parts that were so commonly used on some great bikes, the sheer silliness of worrying about these shake-apart pedals would be overwhelming. Back in the day... I used to define three pedal categories: 1) Disposable, including every Lyotard I ever worked on from the 60s forward. So loosy-goosy that they just weren't fun to take a part, clean, and reassemble. It just didn't improve - or hurt - them much.
2) Worth maintaining, like Campy and some clones, and some Atoms, too.
3) Esoteric, far outside my budget. TA, Phil Wood, and then the Suntour Superbe (yeah, I know they "lifted" the design, but they had the good taste to steal a great design, and improve on it).
But, it's fun to play with this stuff, and there are some bikes that just require these pedals, maybe just to show how fine the rest of the bike was. :-)
BTW, Tom, if the pedals thread on too far, it probably means that you're using pedals for AL cranks on proper steel. I'd probably grind off the extra pedal length. Less destructive types would use washers between pedal and crank.
