Thanks, I connected it like this, but with some cd`s (atm only 1 cd is readable) he hits his end stop, and somehow doesn`t spin up to full speed either...



I`m going to try to attach some caps. What would be a good value?

Hello I have the crystal clock (trichord) with powersupply mounted with 2 wires and no capacitors and working....did you check all the other stuff eg. ...the toc switch....because that is a very weak plastic thingie...

I am suggesting this because you have a cd that gets read..


Anyway my real reason for posting:

GET RID OF THE MAGNET...

Using the Acryl or Delrin Platform and screw puck might be a bit of a hassle in the first place but in my set-up and in my perception it is nearly as "huge" as an expensive clock with powersupply and superregulation...

After loads of cd's I played since starting this project I became cd after cd rock steady convinced

Instruments and voices become much more
"recordplayer-like"...a virtue I have no clue to reach otherwise with digital.....

Thanks for the reply Erik, I checked the doorswitch and its ok.
I tried spinning my clone without a cd, and it does exactly what it does when "reading" a cd:

- Spin up cd ( imho not wel up to speed and slow roll on!!)
- Move laser assambly 1 mm to the left ( it hits his end position after reading)
- Focus the laser (only goes max in, and max out, with no obvious trace of focus.)
- Call "00 / no cd

This is exactly what it does, either with, or without a cd...

I tried all variations on the caps, resonators and such now. Same with the added twisted wires.

To me it seems the laser isnt reading anything (perhaps because the cd isnt up to full speed? ) It just follows the same routine focus everytime.

I checked my PS, for voltage which was a steady 8.02 volt. I`m going to change the diodes now perhaps one is broken and its not reaching into his max current? I`m using msr860`s x2 btw.

Pff, this will be some trouble shoot ;-)


* edit: good point Erik, but no cd`s get read anymore now arg

I am not quite sure if it's just a magnet. I think the mass of a new table mounted on a whole length of a shaft may have something to do here as well.

Changing discs is not really a hassle for me, when approched properly, the process can become very simple.

And yes, that upgrade is much recommended; it is also my impression that the effect can be compared to adding a dedicated clock, as I already mentioned previously.

Okay another "mistake"....

The ring for the motor is not a succes ...the screws to position him opened up the ring...and height together with a perfect 90 degrees seems nearly impossible to get....to much deviation...

I seem to have found a better solution...

Out of a billet copper 12 mm I made a mounting hole nearly covering up the hole motor-encasing...

This time only ONE screw to adjust the height..

It is still possible to detach the motor by lowering it 1.5 mm and attaching the board not to the copper but underneath a strip ebony....by only drilling 2 holes through the copper...

A lot of work so far but I think this is an important bit....

BTW the filed bit next to the motorhole is for the toc-switch...I had to change that as well cause of the new construction...

I have two transports I'm supposed to ship to one of our american DIY'ers south of my border. But, after a recent computer crash I lost all email and contact information. If you are the person waiting for these please respond.

Regards,
Dan

Obviously this is not gonna work yet..but the way the motor is mounted in my 2nd "test-set-up" takes me further for new ideas.

...........................brainstorming.......... .

About my oscilator problem:

There was a small piece of cut-wire inside the laser compartment... I normaly don`t clean up my workspace, but I will from now on!

I had a spare one, so when putting all the parts on the "new" one, I came across that little wire that was obstructing the laser from moving properly.

Glad thats fixed -although kinda stupid.. -

How do you guys handle your mechanism when modifying?

I`ll install the crystal tomorrow, see how it goes. Atm, I`m happy I have my clone up and running again.

Thanks for all the crystal replies and help.

I followed Audio1st's design for the enclosure and mounted the transport onto a marble/granite base. The transport is suspended using 4x 60mm M6 bolts with thick rubber washers to absorb minor vibrations.
