I also weigh out T-88, but not 1:1 ratio like you would mixing by volume. Since I haven't mixed it for a while, I don't remember the exact ratio, but I think you use slightly less hardener. However, mixing 1:1 by weight is probably within tolerance. I also use those tongue depresser-like sticks from your favorite hobby center. I square off the rounded ends on my disc sander to make it easier to get into the bottom corner of the cup while stirring. For small amounts, I've simple used a small square of cardboard for mixing.
