I was checking yahoo japan auctions and found this one:

Since i don´t know on repairing and i don´t know japanese i just can tell i think these are the elusive wheels to fix cd-rom2.
Am i right?

If i´m right in the photos you can see the specifications and a german web where perhaps you can buy it.
Hope it helps.

You are correct. Those are the measurements needed.

That looks the gears that would work for chops two gear solution... the hunt begins!

Hmmm, according to my notes these would replace the original gear of our US tgcd cd players, just have to be glued together. They are the correct thickness and teeth and drill!
I went to the german website, found the english shop site, best discount is 20+ pieces, so 20 of each gear in plastic is $119 euros or $162 dollars!
20 of each gear in brass is $139 euros or $189 dollars!
Still $8.10 for plastic or $9.50 for brass per cd player to fix, hmmm..
And I don't know if that includes shipping...

Hmm.... but with the specs, it might be possible to find them cheaper from another custom manufacturer.

This is even pricier, but it does look like someone found a way to make the compound gear.

Ha, you know what? I have worked on some drives with that gear in it before. I was like, what is up with this clear looking gear? I thought the original gear had lost color funny due to the type of lube people were putting on it.

I had already looked into that. On the original web-site (which may actually be the one you are quoting), he gives detailed instructions on how to modify those gears to work on the CD. The effort is a bit extensive, so that may be where a lot of the cost comes from.

Basically, you buy the original gears, sand the plastic down a bit to make their surfaces rough enough so they can be glued together, glue them in a specific position, then drill out the center holes with a specific size drill bit (done either by hand or with a very small, slow drill). Keeping the two gears co-centric requires either really good hand-eye co-ordination, or a very well machined jig.

I suppose part of the cost is also shipping, and currency conversion.

Just some FYI

By now I am really surprised none of you have simply contacted a watch or clock maker/restorer to do a custom job. They make their own gears all the time, and if you have the correct measurements.....

a metal gear seems like it would last longer but even if it's well lubed, it will probably make a bit of noise and maybe vibration. The softness of plastic has pros and cons.
