So that's good news that I don't need an adapter or replacement crank arms. Thanks for everyone's help in figuring this out!
oh that's too bad, this was getting interesting. only kidding, good news for you

I kind of agree. It was a lively discussion! Clearly the members on this forum are highly knowledgeable. I often come here for advice before going to my LBS because I know I'll get more accurate info on this site.

Because the 1/4 is smaller than 9/16, it should be fairly obvious. The pedal just won't go in. As long as you don't try to jam it, you're unlikely to damage the thread.

You can start with the left side pedal. That's the one that loosens the "usual" way.
Not true! Pedal on the left side (non drive side) does NOT loosen in the “usual” way!!! I.E. “righty tighty / lefty loosey” DOES NOT apply. I’m surprised that no one has yet to point this out.

Unless it's French.

If the French could have had their own totally-incompatible-with-everything-else standard for handlebar tape, they would have.

Now I know. Avoid French Bikes.

Hard enough keeping track of the other standards.

French bikes are pretty cool. Everything about them is weird, true... but at least it's consistently weird. The French had their own standards, and those standards were weird, but, aside from builders like Rene Herse and Alex Singer who were making custom parts in-house, everybody actually adhered to those standards. So French parts fit French bikes, and, although it can be hard to find the part you want, if you can find it, it'll almost always fit.

If you're rebuilding a 1950s Rene Herse custom, you've already got enough money to have whatever you need fabricated for you... which you will have to do. But a 60s or 70s high-end Peugeot / Motobecane / Gitane? They were all standardized, just standardized to a standard that nobody else used. Hell, even the frame tubes and lugs were weird.

To be fair, the French bike standards are not "weird;" they're metric. Which is the system used everywhere else in the world except the United States, and bicycles.

I was scratching my head about using 9/16 without adapter. Now I can put a little weld bead on the tip and open up the hole.
I primarily like one piece over three piece because I prefer real Schwinn bikes.
I've gone over this pedal situation in the past till Im blue.
There are no current offerings off the shelf for 1/2" rat trap or lite weight pedals. Some of the SKS models are offered in 1/2" but will have to be found first. The best pedals for one piece cranks are the vintage ones that Schwinn put on their 1pc crank sport bikes like the Super Sport and Continental. Nearly all of their three piece crank offerings from the 70's on up were Japanese bikes and as far as I have ever seen all use 9/16" pedals.
When looking, also search for vintage BMX pedals, they were mostly 1pc crank bikes and rat trap style.
But the best 1/2" rat trap Ive found is the Atom 440 that Schwinn put on the sport bikes. They came in Aluminum brace post and steel strap brace styles From the early 60's through about 1975.
Another cool way to get around it is to buy a trashed set of these 440's for cheap and rob the axles out of them. Then you can swap them into any of the other Atom models of similar length. I've done that, but it may even work for other types also.
