Random factoid for those interested,when you put a beam in compression the formula for the weight it can hold is P = c * (E*I)/L^2 where P is you load and L is the length. Making a beam half as long actually increases the weight capacity by 4. Similarly cutting it down to a fourth the size increase the weight 16 fold.

No, if it is wood glue (Elmer’s, Titebond) then adding a percentage of water will actually increase the strength of the joint. The water thins the glue, making better able to seep deep in the wood, creating a better joint.

Any tips when using squared cross section popsicle sticks to avoid uneven beams or elements (because of different cross section dimensions between one stick and another)? And… should I cut sticks ends in angle to exactly fit between other 2 sticks forming an angle?
