Post by: Tolvatar on September 27, 2011, 11:47:48 AM: 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.

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...

Post by: Charlie on October 02, 2011, 12:58:14 PM: 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

Post by: GameFreak on October 12, 2011, 11:43:26 AM: 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.
