Drying time. Carpenter's glue takes a while, although if you add a teensy drop of ACC the setting time is immediate.
What kind of carpenter's glue are we talking about here - yellow glue? resin glue? I use yellow glue all the time and it has a pretty short working time. I sometimes wish it was slower to tack up, especially if I am putting large surfaces together. I've never really found a use for resin glue, since it foams up and tends to expand. Yellow glue works for most of my woodworking needs. I haven't built a wood kit in a while - when I did a lot of kit building, Ambroid was the adhesive of choice. What are most people using now for wood kits? CA? Yellow glue is pretty strong, but it doesn't come in hobby size containers. I'm tempted to check out this new 3M stuff just to see how it does.
