Big "V" pushes pull jig to higher level
As a woodshop teacher, I believe in "jigging up" to make projects easy and repeatable, especially because each operation will be repeated by 20–25 students in each class. An example is this drawer-pull jig, which features a V-shape centering window, shown. The window makes the jig work even if the drawers are different sizes. Just center your line in the window, drill, and repeat.
