Another DIY Turntable ....Rega style

[Sergelisses]

Hello

A crazy idea or bad idea !!!!!

I started making a turntable with the elements of a Rega 2 and these dimensions.
Then with:
best elements sub platter and axe
a better insulated motor mount

You can see attached a pdf file with more details

The glass placed on that direct aluminum sub platter is a bad idea.
Any bearing issues are amplified directly and spread across the glass let alone feedback from where its placed.
I would put a softer interface between them and get a thick rubber mat for some isolation

The way it is now this design would add colorations along with the music

I have also an acrylic platter with this sub platter .....perhaps a better solution

The pic is a little out of focus but to make matters worse there is an air pocket
Now right under the platter. A possible resonant chamber
It would appear Rega wanted a TT to make a sound instead of making one dead
Possible budget decisions at work..,

A thick acrylic platter will work wonders and a huge step forward

A thick rubber mat will damp out a platter nicely, probably all you need.

Nice job, but I believe the plate between the bearing & tone arm will just allow bearing noise to easily transfer between the two, not good. One of the plinth's jobs is to attenuate noise between the two, so you should cut the plate in 2 & have a substantial gap between them. Or even better mount the arm on a separate isolated arm pod.

Good luck with the project.

Thanks for your advices

Or even better mount the arm on a separate isolated arm pod.

Next job perhaps

With the original sub platter and the bearing

The aluminum bar wil be fixed on the plynth with screws ( actually it's not done ,i am waiting inserts )

Not saying this is not a valid view, but it happens to be diametrically opposite to Rega's or even Linn's philosophy.

Take it further, suppose you can vacuum down a record against an aluminum vs acrylic platter with this design
Do you think it would transmit a coloration to the stylus ?

The Linn would probably ring like a telephone and The Ittock arm does ring like one.
Terribly colored arm
Both should be dead and transparent and were long bettered by more advanced designs

Some like this “house “ sound and they know what their doing
