Ok here's what you may want to do.

Measure the apporximate weight you need, probably around 10 ounces or so. measure the diameter of your tone arm (1/4 inch). It will be larger at the other side of the fulcrum (1/3 inch).

Go down to Home Depot or Lowes and find several big bolts which will not cost you much. Try these out. When you can get the stylus to balance just barely above the record then that is zero grams. tap a hole in the bolt (1/16 or so) and put in a set screw.

Carefully adjust the counterweight inward so that it causes the stylus to deflect 1/16 inch which should be about 2 grams. you are set.
