Default Hello All,

In this post I'll attach an isometric view of the 2010 version of my Tone Arm.
Also attached is a picture of some of the new parts I've made. The single carbon fiber arm tube shown, has been replaced with dual carbon fiber arm tubes. I've always liked the "Orsonic" head shell and so it seemed natural to switch to dual arm tubes, to take advantage of that design.

Sincerely,

Ralf

The Orsonic head shells are awesome.I'm glad they are fairly unknown.

Glad to see it's not been abandoned. I hope this gets off the ground, it's mentioned it in a (similar) thread over here.

All the best regardless,

Ralf, that original prototype is one seriously cool arm design. Can't wait to see the new iteration.. The CD took a lot of us by surprise or not.. I still remember how disappointed I was with their sound, come to think of it I'd probably still say the same thing today..

Good luck.. And I hope maybe you will offer a kit of parts in the future for this or your older design..

Thank you Kevinkr.
The principle upon which my tone arm is based is very simple, but turning that idea into an easily manufacturable product is difficult. But I am going to try.

Sincerely,

Ralf

Are the arm bearings in the same plane as the LP surface?

Yes they are.
In the 2010 version of my tone arm, VTA / VRA will be adjustable without moving the bearings for vertical motion of the tone arm up or down. The National Association of Broadcasters ( NAB ) allows a maximum of 1/16" warp in an LP. So, if I had a turntable without vacuum, weights or rings to hold the LP flat, I would set the bearings 1/32" above the plane of the LP's surface to the average height of the maximum warp.

Sicerely,

Ralf
