Making half square triangles units is easy; it is a basic unit that shows up in many quilts designs. In the instructions that came with your Tucker Trimmers 1, you have the instructions for making two at a time, yet there is another method we use when we need a large number of pieced units. You will still get oversized half square triangles to trim down, but with this method you make eight units at once. And of course, as with all Deb's methods, every unit will be the straight grain.
