Well tampered labs tonearm
Hi,
Few questions on the well tampered labs tonearm design:
1. What is the significance of the golf ball ?
2. Why do we need a sand filled tonearm (Any real benefits over the conventional methods) ?

Think the "golf ball" used in their new tonearm is for stabilization and adjustment of the antiskate and azumith, and is the bearing of the tonearm...maybe a poor discription here.
The sand filling in the tonearm tube is to damp vibrations.
WTL has done that since their first model arms were released, so I guess they stuck with what they think is a good method of vibration damping.
BTW - that new design TT looks interesting eh.
Cheers

Hi,
1. Can we use a mouse ball for the same purpose in a DIY tonearm ? I think the mouse ball is also precise for the purpose and is also having enough weight to hold the arm downwards from the inverted 'Y' string.
2. In the original arm, the golf ball is immersed in the viscous silicone fluid. I think, the DOT-5 oil used for brakes is a good alternative.
Please comment...

I was in touch with a couple of the people involved in the development of the TT. The golf ball is an integral part of the design, having the density, mass and diameter necessary for the correct damping of the tonearm as well as supplying the right amount of anti-skating. While it looks simple, there was a fair amount of engineering that went into it. This is not just a casual attempt to come up with a gimmick and charge an a enormous amount of money for it.
Bill Firebaugh, the designer of Well Tempered, demo'ed the prototype at the Pacific Northwest Audio Society and it was outstanding. I believe he holds a couple of dozen patents, several relating to turntables (the platter bearing is one of them, IIRC).
At the time, he said that he felt that this was his best sounding design yet, and his older designs were rated very high by reviewers of the major Audio Magazines.

Terry, you has your facts straight, as usual. 
Bill Firebaugh is the inventor of some very innovative designs and deserves to profit from his work IMO.
The point behind the golf ball is that the dimples act as 'drag multipliers', dramatically increasing the surface area of the ball, without increasing the size. It is the interaction of the dimples with the silicone fluid that provide useful levels of damping and control. A smooth ball would not work very well at all.
Sand is an excellent damping material, supressing vibration as well as altering the resonance frequency of the arm tube. It also has the virtue of being available almost anywhere
TIP: the ends of the wand are sealed with wax.

a simple, effective and designed for manufacturing...
using existing, off the shelf components is one way all manufacturers can decrease costs and increase profits. Mr. Firebaugh may have got to a golf ball like object on his own and ended up realizing that a golf ball has the properties required.
If no one else thought of it, who cares? He should profit from his innovative thinking (as others in the audio industry have). The key here is innovation, not creation. Short of the Well Tempered arm, the Schroeder arm comes to mind as being similar in concept, using magnets and string instead of the physical interaction between the golf ball and the fluid.
maybe I'm wrong
anyone know when Van Isle DIY 'fest is on?

Hi,
Understood the importance of a golf ball. Wow! what a great thing. Now, can someone tell me the details on the silicone oil used in the original model ?
@Nanook: The fest starts on July 10. The details is available on the link: http://www.islandmusicfest.com/

Bins and Nanook,
I think that the Van Isle DIY Fest is what was being referred to and the ongoing thread for this year is here:

Just an update on the WT turntable: Those that were at the Vancouver Island DIY Meet last weekend had the oppurtunity to hear the "Golfball" in action.
A friend of mine gave me the TT for my birthday and I took it to the "Spiritual Home" of the Odd and Offbeat: Planet10!
Please note that I'm referring to the people attending, not the gear...
For those that couldn't make it: Well, what can I say except it was a lot of fun.

Thanx for bringing that Terry... it was a gas to see the original prototype....
