Any TT building experience?

Do you have access to Solidworks Steph? If you have the correct extension you can do finite element analysis.

Not a lot of knowledge personally but, my brother in law built my table. He is a machinist and constructed the table using brass and aluminium. The main pedestal is solid brass. The platter is two inch Teflon. The bearing: he purchased a Clearaudio replacement bearing (may have been a VPI), and copied it. The bearing is a inverted ball and thrust plate. The motor is AC. This table is very heavy therefore isolates and controls resonances with its mass. Do to the flexibility of the arm board changing arms and alignments is easy!

Hope this helps a bit and your DIY table turns out successful.

why is that if i may ask?

Sorry Jamie, are you asking me? If so, then why is what exactly?

[karma67]

i was asking why you like using wood

But I wrote that I don't like using wood for this purpose:

Personally I'm not very keen on the use of solid timber for use in turntables.

Have you been on the Easter sherry ?

What the dickens is going on with the lamp in that first shot?

Looks like a lovely turntable mind, congrats.

sorry typo, ok so its clear WHY DONT YOU LIKE USING WOOD?

[YNWaN]

It's not so much that I don't like using wood, just not solid timber in turntables. Even then it partly depends on the wood. The problem with solid timber, as opposed to man made boards like MDF or ply, is that they vary in quality from one batch to another and even within the same piece, they are not as stable as other materials and they have a defined grain structure. All of this is less true of the very hard exotics like ebony but they are not available in sufficient size to make much more than an armboard out of (I've used ebony for turntable bits in the past) - however, the very fine particulate grain of these woods means they are more akin to materials like Delrin (or even Tufnol) than they are to most other woods.

I think that there is a common misconception that items that reproduce music should themselves emulate the construction of musical instruments (turntables, cartridges, arms and speakers). The reality is that the musicians play the instruments - the playback system isn't another musical instrument, it is a measuring and reproduction instrument - it should replay that which it is given and not add random extra levels of distortion. Musical instruments are designed to colour the sound in specific ways, the musician works with this to create the sound they want - there isn't supposed to be another set of distortions overlaid on top of that by the reproduction components.

Perhaps that very randomness in the grain and density of some woods could be an advantage in a fairly massy structure like a hefty TT plinth?

[YNWaN]

Personally I would rather rely on good design than trust in something that may, or may not, exist; but then I'm not a believer in mass as an isolator or 'hefty' plinths as such.
