Hi Tibi,
Very good eye you have, I taped a thin piece of cloth under the puck to see if it can damp out some of the vibration from disk wobbling but not much of improvement.

Regards

Thanks a lot Tibi. I hope to get the new puck soon.
Measuring the disc distance as per Sean's instructions, it seems to be only slightly off (about 0,1mm).

I ll try to raise it slightly and see if this fixes the clicking/bumping thing.

Shiga case project and CD puck dimensions are available in PNG and CDR - Corel Draw format.
You can download them from vicol audio : shiga CD transport

With these files you can build your own CD puck and Shiga case.

Please note, some files have big resolution and may overload your PC.
Be patient till files are opened.

Regards,
Tibi

Well this will make things even worse.
Seems like I need to send to you another CD puck as well.

syklab,

The 19.58 mm was measured from the TOP of the CD Turntable, point A, without a CD or the Clamp resting on it...to the top of the chassis, or point B in your photo.

If it is easier to measure this way...from the Bottom of the CD Turntable to the top of the chassis, or point B in your photo, the measurement is 17.34 mm. For reference, the thickness of my CD Turntable samples is 2.24 mm.

I tried today with a self-made puck made out of 4 CDs glued on top of each other. The wobling was reduced significantly (some remained probably because I glued the CDs in a harry and they are not identical), although the motor was obviously coping to move the weight. I tried with 3 and it seems to behave nicely. Now I am looking for a way to keep them centered. I m thinking of some plastic pieces glued to their edge.

With this change it managed to read some more CDs. However it still refuses to read the Metallica - Metallica CD. It simply quits after a second or two and the CD keeps spinning with inertia until it halts after slowing down but by bit by friction.

I tried to move the plastic head a bit further from the metal plate to match the measurements given above (needs less than half a mm), but it just won t move. I have applied some significant force to it including some self-devised levers to try to move it from its inner plastic and not stress the disc base, but it just won t move... I m scared I might break it if I try any harder.
