thanks i am watching your work
a lil polish after taking some 400 grit to the rough parts and then 600 again over that, using some 5mm and 2mm hex wrenches as sanding blocks to get into tight spots. None of the hardware stores in the neighborhood have higher than 600 grit so this might be where I leave it for now!

I have one in my parts bin too, waiting for a project, unfortunately I seem to migrating to mostly sram, and mostly old 10 speed sram.

im all 11+ though sup does have one 10s dynasys bike. so it went to @Andrew_Andeson i think
Ayy it’s me
@jawn_does grey ano derailleur shifts gears flawlessly on my brevet bike

The deed is done! Had to do more hacks than I expected and may still have a hack or two in my future with this derailleur, but it is silver now:
It’s beautiful! Or at least it’s as pretty as I could get it with the pitting some of the NaOH caused and from me not having anything finer than a 600 grit to sand it down with. Now for all the hacks.
This time I protected the main mounting threads with some putty, as the last solution took an M7 down to an M6 on the outer cage plate and it wouldn’t mount. Somehow the mounting bolt came free from the plate, though (it’s a press fit) and I had to do some finagling to get it to screw in tight to the body of the RD.
The threads I forgot to protect were the little ones that hold the screw that keeps the main spring in tension – the little round buy with the phillips head on all these shimano RDs. The NaOH ate what I guess is an M4 hole up to about an M5. I had to tap it and run a low-profile water bottle cage bolt in there I had lying around from some wolftooth kit. It juuuuust clears the guide pulley:
The other threads I also forgot to protect the first time around were where the tension pulley mounting bolt threads into the inner cage plate. What was (I think) an M5 hole is now about an M6, and until I find a longer bolt that will fit in there, a couple threads (and some threadlocker) are holding a nut on the other side of this bolt.
I vaguely recall buying a ton of nearly-right screws and nuts from various hardware stores on a past adventure getting a front rack to mount on an '80s lowrider fork with un-threaded mounting holes, and while that was a very annoying set of trial-and-error parts store runs, I’m now vaguely happy that I have a tiny drawerset full of various make-it-work hardware.
I’ll see how it rides, and if a longer bolt keeps everything in place or if I’ll have to buy another inner cage plate and just oven-cleaner it.

and by complete chance of bike compatibility, these 6 spd Deore XT thumbies on here have almost the exact same pull as 10 spd dyna-sys, so these actually do index, at least in the middle gears. I might futz with it some more in the future so it does gears 1-8 and I can engage friction mode to get the last two granny gears, or something
this makes me feel like i should have maybe worn gloves when i stripped my SLX cranks with drain crystals.
also fuck yeah Acid Bath.

at the very end of this process, I was just taking a cage plate out of its little fizzy bath to rinse it off in the sink. I was picking it up with pliers, so for once I didn’t put a glove on that hand (I have a little cut on it). As I’m lifting it up, someone decides to pull a long sewing needle out of the fire they were keeping it in, and delicately but firmly pressed it directly into my cut. At least, that’s what a single drop of the stuff running down the pliers and onto my finger felt like. It’s always the one time you don’t wear gloves!
that’s gonna collect gunk real quick, use a setscrew from the outside

Ratio Technology keeping it up, I’m thinking their stuff may figure in a bike i’m sketching out.

just put in a boltdepot order and threw some set screws in there! I took this thing around the block and yeah, the bolt that’s in there doesn’t really interact with the pulley, but in the really low gears when the cage is stretched out, I feel like the chain rubs on it. Def coming out
I wonder if they had to do the jockey wheels so they would work with the flat top chain cos I am pretty sure the dangler pull is good to go anyway. Looks great.
