VTA adjusters just extends the height of the arm by a few milimeters and they just need to be made of a solid enough material to ensure the arm mounting is completely firm and has no play whatsoever.
Orbit is a high performance DIY turntable based on Rega 24V decks. It's very easy to make using a moderately well stocked home workshop. In my opinion it competes well with decks costing a lot more than its sum of parts. It uses a fairly conventional design so that it is easy to fit the original Rega lid back onto it, this is important as a lid protects the fragile stylus when not in use and prevents dust reaching the deck.
<img class=" titleimg" alt="" src="/images/audio/turntable/tt-complete2.jpg"/> Although my first turntable prototype worked quite well, it had a few issues, each of these is looked at here: The area under the platter was too thin, and tended to concentrate vibration around the platter main bearing sleeve. This was fixed by brute force to avoid vibration in the first place (a very large granite / MDF block below the plinth). The positioning of the motor and circuit led to some noise, and only earthing to motor prevented it.
<img class=" titleimg" alt="original TT" src="/images/audio/turntable/tt-complete1.jpg"/> Before my most recent turntable build, I had tried a couple of earlier designs. The first of which was a Rega deck with a couple of IsoKinetik modifications. I've gone a long long way since this, but I keep it here for historic purposes. Starting out with a P3-24 deck. My deck started life as a refurbished P3-24 unit, with no mods made to it.
