Kitchen Scale for Measuring Thread Tension

[friquant]

Was planning to keep it intact, and just tape the thread to the top plate for measurement. But when I took it apart to disable the Mode button (so it will always stay set to grams), it looked so easy to repurpose...

 

Here's a link to the original 500g kitchen scale I bought. And a screenshot:

 

Drilled two holes in the upper right and reused the original screws to mount the load cell there.

Added hot glue to keep the wires from being damaged from being tossed around

Taped over the digits to the right of the decimal place so they don't distract.

Here's what I use:

Something I used to adjust my trigger pulls looks like it can easily be adapted. Take a plastic cup, make two holes near the rim, opposite from each other and put a wire through the holes. Now you have what looks like a miniture paint can. Tie your bobbin thread to the wire. Lift the cup up while holding the bobbin. Slowly pour water into the cup until the bobbin releases the thread. Weigh your cup with water on a kitchen scale.

Once you have a desired weight, put your empty cup on the scale and fill it to your target. Hang it from the thread and adjust your bobbin until the thread releases
