The plate is made of 2mm steel, the hole has a diameter of 10mm and is not threaded and rotates freely on the mounting bolt. The bolt has a tight fit in the threads of the drop out, because it must not be tightened completely otherwise the derailleur wouldn't rotate. The mounting bolt of late Jubilees has even "factory scratched" threads (the dark line across the threads) to hold the bolt in the drop out without an additional nut.

-----Original Message----- Subject: [CR]Huret Jubilee question
I'm puzzled about a Huret Jubilee rear derailleur. Obviously, it is designed to be mounted on a claw, with a back-up nut. You apparently can't mount it on a Campagnolo drop-out; you can't tighten the mounting nut, or the derailleur won't swing forward and back, and there is no way to use a back-up nut as with the claw.
Apparently, it is possible to obtain a special mounting plate so the derailleur can be used on a modern drop-out. There are some pictures of Jubilees with these on the CR site, and I've seen a couple on eBay. However, the view of the plate is obscured, and I can't imagine how this would work. Is the plate threaded, so it acts like the back-up nut (although on the front side of the hanger)? Or is there some other arrangement?
I've little hope of finding a plate, but I'd consider trying to make one if I can figure out how the whole thing works.
Thanks in advance--
