Yet more headset issues...

A 1" threaded BMX headset should screw onto a similar ISO fork with no
problem as I'm reading.

Am I right? Will a BMX headset fit an ISO fork? Never mind the frame
or the stem... just the fork. (It'll fit my frame and I'll cut a shim
for the other.)

Yes; I have done this many times. Depending on what you have in mind
for the stem, you might have to use a top nut from an ISO headset,
since the hole in the top of a BMX headset is smaller than an ISO stem
quill.

Dia-Compe makes a threadless BMX headset, if that appeals.

I think I'll cut a precise shim and use the BMX quill

Well, yeah, but the bike predates that. If I were a stickler for
historical accuracy, I wouldn't be dropping a 'bent fork into it...
but I only paid 9 bucks for the fork on eBay.

Thanks for the help!!!

It might be tough to insert the shim if the top nut is from a BMX
headset.

Shim stock .020" in thickness should be OK for the job. Given typical
bike industry tolerances, .025" might be a better fit.

I'll turn it and JB weld it in before I install the fork... famous
last words: "Don't worry; I do this all the time!"

(Usually followed by a loud crash.)
