My scale is a digital powder scale that measures in units of grams and grains. But a beam scale will do just fine. If the instructions say a 2 to 1 ratio then put weigh one part and add the other till you get the right weight. exzample 1 part a = 1oz and 2 parts b , weigh out 1 oz of part a and then add enough part b to get 3 oz.

I've never thought of using a scale; do you use a digital powder scale or a beam scale?. I normally just go by the graduations on the bottle. I've never had a problem for years until now. I think I just got a dud.
