Zeroing the tensio

Webmaster

In a previous blog I demonstrated the spoke tension utility available on this site. It works with the Wheel Fanatyk digital tensiometer and data cable.

When you place the tensiometer on a spoke, it’s ideal if the tool reads zero but sometimes that doesn’t happen because of the spoke itself — they’re not perfectly round. If you don’t zero the tensiometer, you introduce error into your readings. Zeroing the tensiometer is easy but you experience a delay while it resets and it requires the use of both hands. In short it takes a bit more time.

With the introduction of the data cable I had the idea of skipping that step by doing the zeroing in post-processing instead. How does it work? Suppose you place the tensiometer on a spoke and it reads 0.01. Instead of zeroing the tensiometer, send that reading to the software by pressing the foot pedal or send button on the data cable. The software understands this to be a baseline reading so it pops up a dialog box with the initial value and prompts for the final reading, which you send in the same manner. Then the net value is calculated, the spoke tension graph is updated and you carry on with the next spoke. At no time do you touch the keyboard or mouse on your computer so the workflow is very smooth. I’ve built several wheels this way and it becomes second nature.

To me this is the coolest thing in wheel tooling in a long time and it’s remarkably inexpensive. In part that’s because I offer the software part for free — not even ad supported — which I’m happy to do to support the wheelbuilding community. If you need spokes, support me by shopping here.

Short vacation

Webmaster

SpokeService will be closed from June 20 until June 24 for a short vacation. Orders placed during this period will ship on June 25. Emails and phone calls will be returned on June 25 if not sooner.

As thanks for your patience I’m offering silver DT Swiss nipples free with each spoke ordered until midnight on June 24 (max 75 per customer). These nipples use standard 2.0mm threads, compatible with all spokes sold here. To take advantage of this offer simply ask for them in the order notes field on checkout. Please specify your choice of aluminum or brass material.

Autograph tension

Webmaster

This is a video of the new Wheel Fanatyk tensiometer, equipped with a deluxe Mitutoyo gauge. The terrific thing about a top end digital gauge is the ability to connect to a computer (an optional connection kit is available from Wheel Fanatyk). So what do you do on the computer side? I improved my spoke tension utility to accept input directly from the tool without keyboard interaction. After each reading the software advances to the next cell automatically.

I also added a new software feature to eliminate the need for zeroing the tensiometer but it’s not shown in this video. Stay tuned for a future blog post explaining how it works.
