Vintage Campy pedal axle cone nuts different sizes?

[NHAero]

Aaargh
I have a pair of Campy Nuovo Record road pedals from (I think) 1972, and a pair of Super Record Pista pedals, the ones with the black alloy cages and titanium axles. The cone nuts are recessed from the face of the pedal body so required a special Campy wrench with an offset that fit inside to grab the flats on the cone nuts.
I have been watching eBay and other places to buy one of these wrenches and finally I found one from the UK and bought it. Well, it doesn't fit the Super Record pedal It turns out that the major diameter of the Record cone nut is 15mm, but the Super Record one is a bit over 16mm. The wrench fits the Record pedals.

Are there two of these special wrenches? Will I ever find one that fits the Super Record cone nuts?

Not sure which wrench you have but a number 710 wrench is for SR pedals, titanium spindle.

I am unclear how that would work, as the cone is recessed in the pedal body and the wrench I just bought has an offset to reach into the pedal body.

Do I understand the problem correctly in that there is a recessed cone nut with a lock nut on top of it - so the issue is holding the cone nut while tightening the lock nut?

Exactly. And there should be a lockwasher between the two, which I believe is housed in a recess in the cone nut.

Marc, I thought so. I have the same pedals (I think...)

I serviced them without the proper too without much fuss. As you'll know, once you get the lock nut off, there shouldnt be much tension on that cone nut, and the lock washer should ensure (more or less) that the cone nut does not turn with the lock nut. It would be pretty easy to get apart.

On the way back together, I just held the cone nut with a flathead screwdriver against the nut flat while tightening the lock nut, with the pedal chucked up in a bench vise. The lock washer makes the job pretty easy.

I have to imagine the proper campy tool does exist, but I dont think you need to chase it if servicing the pedal is the intention.

Nice pedals!

I've definitely messed with the road version without the correct tool, as you say, but in my old age I like to have the right tool for the job if possible!
