Class received a lesson in fractions, and created a chart to help understand how to glue up a "blank" to make the toy from.
The wood available in class starts as "4/4" lumber (e.g. rough lumber that is 15/16ths of an inch thick.) After being milled to square the lumber become between 3/4" and 7/8" thick. So in order to make a blank two or more boards of these thicknesses must be glued together.
It is VITAL to practice a glue up before actually spreading the glue. It is super helpful to have a classmate standing by to help you, both with the practice, and with the actual glue up.
Squeeze out must be removed 30 minutes after clamp pressure is applied.
Don't attempt to get something glued up with less that 45 minutes of class time.

Glueing Up a Blank
Wood glue requires to flat surfaces to be glued together under pressure. Clamps create a 90 degree cone of force. When glueing panels together it is often / usually necessary to use cauls in order to create cones wide enough to provide pressure all over the blank.
