Thanks for the info ReinoutdV.

I've been eyeing some of my cf tubes again because of your recent work. I was planning on building a new tonearm with one after I finish a current project. Cutting the shafts to length neatly was always something that bothered me. I guess I can always try the dremel technique.

Capt Zach,

If you're asking about cutting CF to length, a cheap ($5) hardware store tube cutter worked surprisingly well on golf club shafts.

Hi,

Finally, I received the carbon shafts for the arm. I am planning to try out the 9" arm. See the attachment for the details. Also, can we use the original arm flat disc concept (as explained in the patent paper) instead of the golf ball ? Please suggest.

Best regards,
Bins.

Good luck and enjoy both the project and the completed arm. WTAs are excellent arms. I built a clone of the original WTA years ago and used it for a very long time.
Bill Firebaugh mentions somewhere that WTAs require very little antiskate force. I would like to mention my thinking on the reason for this. Immerse an object in silicone fluid, the thicker the better and drag it through the fluid you will feel resistance. The faster and harder you push the greater resistance you will feel. At low speeds the fluid flows around the object easily.

With conventional pivoted tonearms the skating force is greater at the start of the record and lessens as the arm travels across the record. Attach an object to the arm and immerse it in silicone fluid and there will be resistance to the object moving through the fluid. As the skating force lessens with the position of the arm on the record the pushback of the fluid will diminish also. The dimples on the golf ball provide lots of little paddles pushing their way through the fluid and being pushed back less as the skating force diminishes. So the WTA has self regulating antiskate force. The initial antiskate force is set by the angle and rotation of the suspension strings. IMHO this is by far the best solution to the skating problem existing today. To my knowledge no body has advanced this analysis of antiskating in the WTA. Comments please.
