My own ShigaClone CD Transport Version

[Algar_emi]

I'm building my own version of the ShigaClone CD Transport, refer to original thread "Finally, an affordable CD Transport: the Shigaclone story" for details. The Transport mechanical design is greatly inspired from Peter Daniel own design.

Here the external 12Vdc supply. It is assembled into an aluminum cylindrical enclosure. I was able to mount the big power transformer 266LH25, the two MSR860 rectifier diodes, an AC inlet socket, the output shielded cable, a junction terminal block and an inline fuse socket.

The transformer is mounted on rubber insulator and held in place with only two screws.

The front will be made of wood, as the transport main platform (butcher block).

It will rest on two aluminum round bar, as the Labs 47 Power Dumpty supply.

Here the inside. It is rather compact.

And the rear power supply view.

I did a complete AutoCAD drawing of the transport and the EZ31 parts that we need. Scale in inches, sorry guys using the metric system.

You can use it to test your own enclosure dimensions.

For the one that don't have AutoCAD, here a top and front view of my future transport.

Here the Transport wood base and all metal parts before assembly.
I'm using 1.5"X2" aluminum bars, 1.5"X0.75" brass bars, 3/16" copper base plate. The front aluminum channel section will receive the buttons and the display. The transport metals need finishing. The front display metal section is already very nice.

I completed the Power Supply. The front wood piece is done. The supply will rest on 1 brass round head nut on the front and two rubber feet at the back.

The Aluminum and wood of the supply will match the transport materials. Here a complete view.

Lovely job you've done there

Thanks Algar for pics and ideas.

Could you please detail springs specs, if any and estimated top transport weight.

Cheers

Thanks Quan. I'm not sure about the springs just yet. For the moment they are the EZ31 battery connectors springs that I recycled. The top platform springs forever if I excite it. Oscillation frequency is about 2-3 Hz, but really need to amortized. They are probably not stiff enough. I tried to put foam into the spring without any good result.

Top platform (metal only) weight is: 4.980 Kg

Spring: Conical shape, Lenght 29mm (uncompressed), Base diam. 17mm, Top diam. 10mm, wire diam. 1.22mm, 4 springs compress to 23mm when loaded but the platform 5Kg.

Here my what I call my Control Self. It is the original display PCB, cut to fit and accept the two front toggle switches (PWR and TOC), with on top the relocated switches STOP-FB-PLAY-FF-RPT. These buttons are made of chromed brass. Again, they are recycled antenna tips from the EZ31 itself. I re-used the original plastic LCD window.

The PCB will be mounted from the back, into the butcher block. The top switches will be connected to the PCB using small wires. These switches are the original PCB ones. They will be mounted in the wood block, into drill holes and fix using glue. The 2X2 aluminum channel will be screwed on the block from the top with to stainless steel allen bolts.
