I use TBIII to get the extended open time. The face frames, front and back are already glued together so basically I have 2 face frames, 2 sides, a top and a bottom, and a center vertical panel. But I do have about 48 feet of groves and dado's that have to be filled with glue in about a 15 minute period for each upper cabinet. These all lock into each other so clamping just holds it together should something like this happen. ;~)
It all goes together like a puzzle, on top of my spacer blocks, thank you Swingman, and then as a last step I add the clamps.
