These should help. Unfortunately, some people are unable to read the strange font I used. I'm not sure why this is unless they are not hitting the icon to raise the picture to full size. In any case, I found it too tedious to go back and redo the drawings. For the price, they are a real bargain.
{There is an orange, barrel-shaped icon that appears in the lower right corner of the picture- it takes a while to load and appears and disappears with mouse movement. Click on that and the picture reaches maximum clarity.
