Hi meatstick8,
find a small scale that reads in grams or ounce (you will have to do the conversion) place the assembled extender base down on the scale, press till you have reached the first mark on the tension rods, look at the scale for gram readings. This is mentioned in several places in the forum and can be found using the search feature of the forum.
