Lightweight turntable project

a couple more pix

Hi guys:

Just a couple more photos so that you can see how this was done from the underside.

and one of the motor cutout - first from the top...

The grey mounting plate is, in true flyweight fashion, a peice of thin sheet steel cut (with scisors) from the bottom-panel of a cheap receiver.
The mounting gromets are the originals from the B&O table.

and the motor cutout from the bottom. I probably could have mounted it in a hole rather than a cutout, but I couldn't find the arbor for my holesaw (this whole build took 2 hours).

and the last refinement (Ok, I might varnish it - or I might not 😀 ) happened today - I mounted my nude Denon DL-103. How does it sound now? Even better!

I got to do about 3 hours of critical listening today and ran through the whole gamut from Jazz to Rock to Classical. This little table realy cooks - amazing detail, very stable soundstage, excellently musical. And I don't know why the DL103 has a reputation for being bass-light - it sure isn't here.

Let the music flow

Nice job!

In regards to the funk firm, I wonder why nobody's tried making a light platter like the anchroplat they sell. AFAIK, its just explanded pvc, a pretty cheap sign board material you can get from just about any plastics supplier. I would think that it would sound a lot better than mdf.

lightweight platter...

Capt. Zach,

I agree. Actually am designing a super-duper lightweight platter. But if a super lightweight platter is used, something has to be done to increase Inertia. There are only 2 ways I am aware:

• increase mass
• use more than one motor

There is a fine line between a lightweight platter and something "too" lightweight. The concept of ultra-lightweight platter, and Colin Chapman, who added horsepower and engineered in lightness Lotus cars), could work here. ...hmmmmm.....
