Quill stem adapter without using the lock nut

I figured it would work but thought it might be tedious to set-up, taking several tries to get the pre-load correct. Glad to hear it worked out relatively easiliy.
Ideally, for this set-up, you need a quill adapter with a recessed expander bolt so that a star nut could be installed above it and you could load the stem and spacer as per a theadless system. If a thick spacer could be manufactured to seat where the adapter changes diameter, this would allow for a recessed expansion bolt. The problem is finding an expansion bolt with a small enough drive recess to allow the allen key to pass though a standard star nut. This would require about a 4mm recess.

I see these threads re threadless stems and ask why? Not disparaging the OP, but am curios as to why
I don't get the "more modern" aspect as the function is the same with the classic quill stem.
These always seem to be a bit cobbled together (except for the colonel lloyd one)
I find threadless stems to be butt ugly in general.
I can see the ease of getting bars off and on if you have the full removalble face plate, but that is th only real advantage I see

That's not what this thread is about, but threadless stems are lighter, stiffer and easier to adjust than threaded systems. I'm not hating on quill stems (all but one of my bikes uses a threaded headset), but it'd be disingenuous of me not to admit threadless is a much better way to secure a fork to a frame and stem to steerer.

I underestand this is OT and maybe I should start another Thread. I understand advantages of threadless, if using a full threadless systems, headset, fork, stem. But what advantages are there to trying to put a thread less stem on a threaded system?

You mean using an adapter like the one I show on the first page? There's not much of an advantage, no. You may save a little weight, maybe not. You could get a stem with a removable face plate, as you say, which could be more convenient for some. I did notice that, despite being two pieces, the adapter + Cro-Mo stem I'm using is stiffer than any aluminum quill stem I've used. Some may hate that, I dunno. I like it.

I agree. Any messing with the stem would require bearing adjustment again. Not a big deal if I'm in my garage and have access to the proper tool. Roadside adjustments would need to be avoided.

I like the ability to use an over-sized bar
I like to use bars with ergo bends that don't fit through quill openings
I am big and tug on the bars a lot when climbing and this setup feels better to me
Different strokes . . .
