Washer hack for Huret dropout?
I saw a pick of a suntour derailleur on a huret dropout aided by a washer modified to replace the 7 o'clock tab of a typical campy dropout. If I could see the washer alone it would help. Just wondering if anyone could point me to such a pic?
My new competition has lovely huret derailleurs and I want to keep them lovely.

I have one on the slab. I’ll take some pix and measurements for you.

What I did once was to find a thin steel washer that fit over the derailleur bolt. Then I clamped just a small edge in a shop vise and hammered it over until I had just a small lip bent over. Then I installed a modernish shimano derailleur, using the washer lip to bridge the gap between where the Huret tab is and where derailleur wanted it to be. It worked well enough to run 8spd STI levers on the bike with probably 28t cassette.
I'm pretty sure I still have that washer, I'll see if I can find it and take pics of it in action.

I made a convoluted "fix: to do that for the first year of my ownership of a Raleigh Competition. Forget what I did. Worked well but making and installing it wasn't easy. That bike then went to be stripped, inspected and repainted as I didn't trust the workmanship. While there. the dropout was modified to the new standard. (I assume with a piece of steel brazed in. Bike also got the seat lug pin area completely overhauled to the current seatpin standard, WB bosses and braze for the lugs! Enough work that I never asked about the hanger stop details.)
Thinking about that washer just now - I wonder if you could shape a little piece of say 1/4" plate 6061 aluminum to a "parallelogram" with arcs instead of circles top and bottom to (looking from the side) fit the hanger and stop with the back flat of the shape serving as the new stop. Drill a countersunk hole in a large fender washer and a matching tapped hole in the new small piece. (It would take a tiny screw to do this but it only needs to keep it from falling off.) Ace Hardware probably has the perfect flat head metric SS screw for the job.
I'd get a stainless steel fender washer with a smaller inside diameter than the hanger bolt and drill to just clear the bolt. Might well have to cut down the rest of the bolt to clear derailleur, chain, cog, etc, leaving just the tab for the new piece.

This washer was found on a Super Course MkII with Huret dropouts, required to mount the Jubilee RD!
A brass washer might work as well. Break out the drill, vice and hammer!

Not my bike. Not my Project. All appropriate attribution. I found this well documented hack as like the author I've an early 1964 Schwinn Super Sport with the Huret hanger.

Maybe you saw mine (or one like it)? Here's a Flickr album for the bike:

Scroll down and you'll see the fender washer marked for cutting. They were whatever was right at the local hardware store. Buy a few. I think it took me three tries to get it right, but I eventually did.

I needed another one and the shape of the washer reminded me of a 3/4" copper pipe cap. It only took about 25 minutes to fashion this one from copper. No hammering required.

If I had my super sport back and I wanted to do this, I would probably try to scrape off the paint right there, and stick a little piece in with my wife’s big stained glass soldering iron.
