This video is of an experiment to see how clamping pressure affects the strength of wood glue joints. If you want to skip a head to the fun part, it stats at 8:37
In this experiment I use Titebond III to glue red oak boards together with clamping pressures that range from about 1.2 PSI to 1400 PSI, I then use a Fabco Pancake Air cylinder to apply force to the glue joint till it breaks. Since pressures higher than typical single or two stage compressors provide are needed, I use an SMC VBA-10A Booster Regulator to get the pressure up to the air cylinder rating of 250 PSI.
Another very good video on glue strength is "Glue Myths: 1. End grain" by Patrick Sullivan on his channel linked below.
