Campagnolo C-Record dustcap extractor: how to build it?
HI
This Campagnolo Record/C-Record dustcaps extractor seems impossible to find nowadays, or they ask you crazy prices.
I'd like to build something like that, has anyone already tried to make it?
If so, I mean tested & working, can you share the project?
(I had opened a similar topic, they pointed out, in probably the least suitable area of the forum, sorry)

My C Record dust caps have always come off pretty easily with gentle persuasion from a small flat tip screwdriver. Doesn’t seem like it would be too difficult to fashion a tool from a small thin steel piece and a threaded bolt. I’ve heard of people using battery terminal extractors although it would likely require a little filing to thin the bit that fits under the edge of the cap.

A few minutes on the grinding wheel and probably would work, I would dress is after grinding.

It looks like an hybrid kit, but this is what I bought on eBay.
Guess what? The seller's description? "Hub C-Record, NOS".
Guess what is written on the Campagnolo box? "C-Record/8sp" again!
It's was sealed kit, never opened, so no one has ever mixed the hubs.
Campagnolo quirks, but no need to point that out again when it's very clear (from the photo above) what I need.

Solved!
In a flea market I found an original Campagnolo extractor, but it cost too much because the seller was asking 150 euros!
So I asked to see it up close, I took out a sheet of squared paper that I always keep in my pocket, I put it as a background and I took a series of photos with my cell phone. From the side, in profile, above, below, etc.
In the end I compared the photos with the squares of the squared paper, and I drew the profile on paper. I then took some sheets of steel, glued the piece of paper with the profile I drew on it, and cut them with the dremmel to create the body and the two blades, which I went over with an abrasive rotating blade and sandpaper. I then welded a thicker bar in the center, which I drilled and threaded.
I immediately bent the final part of the blades, supporting myself with a vice and a bench goniometer.
Steel is elastic, you have to bend it a little more than the measurement, and then correct the angle. Then I bent the two blades, keeping the thicker bar as a reference point which, being very thick, does not bend.
I finally took a screw and glued the head into the knob of a cabinet drawer.
A very artisanal process, but I somehow replicated the extractor into a prototype that works quite well.

According to Velobase, there was an odd version of the C-Record front hubs kit, called "C-Record/8sp", a kit with on the front hub the same dust caps as the Record, and on the rear hub the same dust capas as Chorus 92 (I have this kit).
