RD alignment, non-dropout, non-Campy hanger

Finishing up my Gitane with, among other things, a Simplex 543... need to get the shifting right. As the dropouts (stamped, no hanger) did not look correct, just got a set of Park FFG-2 alignment tools. To my eye, looks pretty good now in terms of dropout alignment. Derailleur still looks, sounds and shifts "off". By my eye, the derailleur hanger "claw might or might not be the next object of attention. Again, just by my eye, it might be off in the "roll axis" with the bottom of the derailleurs closer to the centerline of the bike than the top -- but also in the "yaw axis" with the derailleur pointed toward the centerline of the bike when viewed from above. Tweaking the claw sounds in order, but "I think so" is not good enough. And as stiff as the claw is and as readily as the dropouts moved using the FFG-2, will "tweaking" in place merely bend the dropouts again instead of the claw?

So, started thinking about a Park hanger alignment tool, like the DAG-2.2,, etc. But, the Simplex claw is unlike, say, a Campy, Shimano or Suntour mounting: the hole is not threaded, and smaller (micrometer says about 9.25mm) so that tool probably won't fit (I left a message at Park, but suspect what I'll hear). Somehow I suspect that later (Delrin Era and later) dropouts might have a similar mounting size... what do people use? Seems like there should be an adapter bolt.

Here's a picture, not that I think it's useful. Also, I see an older topic showing a homemade tool, which sounds great except for the 5-1/2 hours it takes to bore a hole in angle iron without a drill press.

An idea, I haven't actually used: Take an long-handled rachet with an allen bit and insert it in the derailleur pivot bolt - DONT TURN THE BOLT, but rotate the rachet wrench the "loose" direction. This kind of mimics a DAG-2.
You could even stick a bolt into the wrench handle [hanging hole] to act like the measurement guide of the park tool

Sounds like a viable solution for some, with two caveats: (a) the RD needs for the mounting bolt to utilize an Allen Key wrench in the first place... and this one does not, and (b) that methods provides for a way to bend, but not a way to measure whether the bending was done correctly. Unless your ratchet handle is very long and the fit of the Allen wrench is very wobble-free.

So, I'll probably try replicating what I see in this topic: Home Made Hanger Tool

No need for a drill press, an electric drill will work fine. Angle iron is relatively soft and not hardened. Just start on the flat side.
I built my own out of square tubing.
Second from the top.

Well, I do have a beefy 1/2"-drive Milwaukee drill; I would not attempt with my little cordless unit.

Right now, what's stopping me is my efforts to only visit Home Depot once per month for Covid reasons, and I went last week. And hopefully their weak stock of bolts includes some Grade 8 stuff and not the usual junk bolts.

So, the question is, do I want to ride the bike, or not? Something is definitely twisted, and I really do not think it's the derailleur body; but where the chain enters the lower fully on its trip back from the chainwheel, even on the center cogs the chain is riding pretty dramatically off to one side.

Wow, perhaps a topic "how to make your own shop tools" is needed!
