Trying to mount a Suntour rd on a Huret dropout. I know this has been covered in multiple threads, and I am familiar with the basic principles.
I am after something specific: on one of the other threads, someone posted a picture of an adapter they had made from a 3/4” copper pipe cap. I have been unable to find the thread, and I foolishly neglected to save the picture. Can anyone point me in the right direction? Thanks.

I haven't found any copper pipe methods, most options are modifying and bending a washer
The frame builder option

and here's the BF thread where I found both of those:

Doing a Google search turns up a lot of "reverse" hits, where someone wants to mount a Huret Jubilee derailleur on a Campagnolo-style hanger. What you want is an adapter that makes a Huret derailleur hanger (with its stop at about 4 o'clock) look and work like a Campagnolo-style one (with stop at about 7 o'clock). The trick is fashioning something that's thin in the transverse (axle axis) dimension, but thick where it's making a new stop for the derailleur, and where it butts up against the Huret derailleur (either at the 4 o'clock stop, or at the "neck" where the hanger meets the dropout, further CCW).

That’s the one! Thanks.
