Spoke Tension Calibration

As part of my new release I wanted to verify that my reading were accurate.  I used a Park TM-1 in the past, but the precision on the TM-1 is in units of 10 kgf or more, and the accuracy of one that is several years old and has been tossed around in a tool box is suspect.  So I built a custom tension calibration rig.  The idea is to measure the tension directly using a hanging scale, then use that to calibrate my app, and my TM-1 while I am at it.

Here is the picture so you can see what I am talking about.

First, with no tension on the spoke, the hanging scale is zeroed (tared).  Then the spoke is tensioned to a set amount (115kgf in this case). The reading on the TM-1 should match, if not adjust the TM-1.  In my case the TM-1 was off by about 10kfg.  I adjusted and it matched the app much better than before.

After calibrating my TM-1, I tested the app performance and verify that the reading are accurate. \

Overall a useful tool for a shop or anyone who is building large quantities of wheels.

I am working on three major things for spoke tensioner.

1) An input slider that you can set to control the volume level of the input microphone.  This will allow for tuning in quiet room as well as a noisy environment.

2) A pre-filter for the audio.  Currently I am post filtering the audio.  I am moving to "The Amazing Audio Engine" to allow more control of the input and better tools in addition to adding this prefilter.

3) Calibration based on a hanging scale, a spoke under tension and a Park TM-1 tension meter.
