Updated deflections

Webmaster

From time to time tensiometer manufacturers update their conversion charts. While changing charts may seem counterintuitive there can be good reasons to do it.

This week Wheel Fanatyk released a new chart for 2015+ tensiometers and my spoke tension visualizer has been updated in tandem. Download a copy of the latest chart from their official location. (Wheel Fanatyk is the authoritative source but I’ve mirrored the current charts as well: for original model and 2015+ model tools.) This update also includes support for 1.65mm spokes, specifically for Sapim D-Light. D-Light is supported with Wheel Fanatyk 2015+ and Park Tool TM-1 tensiometers.

As of today the conversions in my spoke tension visualizer should be up to date with current manufacturer data for all tensiometers. If you see a discrepancy, please holler.

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.

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.

Two Wheel Fanatyks

Webmaster

I’ve gotten a handful of reports that my spoke tension visualizer isn’t working with Wheel Fanatyk tensiometers. In all cases the problem has been incorrect tool selection on the setup page. Take note there are two choices for Wheel Fanatyk users: original and 2015+ models. These tools have different tension conversion charts so it’s important to pick the right one.

Spoke tension utility update

Webmaster

This week I made a small change to my spoke tension utility just for Wheel Fanatyk users.

The scoop is you can enter deflection values in different units and the software will figure out what you mean. For example, you can enter the value 0.31 as zero-point-three-one or point-three-one or as three-one. Whether the units are millimetres or tenths or hundredths is now inferred and normalized for you. This is a time saver if your decimal key is far from the number row and, like me, you’re without a numeric keypad. It’s especially helpful if you’re entering data with one hand while holding the tensiometer in the other. Existing functionality is not affected so the change can’t hurt.

This is small update but saving a keystroke or two on every entry adds up to a cumulative savings. I hope wheelbuilders (who understand a lot of tiny operations add up to something remarkable) will appreciate the change. Making things better and continuous improvement are always on my mind. If you have any comments to share, please send a message. I know there are users as far away as America, Brazil, Britain and Japan. Your feedback influences future enhancements.
