What's worse than waiting for paint to dry?

What's worse than waiting for paint to dry? Waiting for glue to dry. Especially when you have to sit there and hold the pieces of the model together until it's hard enough to stick. Especially annoying when you're almost guaranteed that the piece will just fall apart again seconds later when the glue sets enough to become brittle.

This is another reason working with the tin models is a pain in the ass. Not only do they not look as good as the plastic ones, you can't get the parts to stick together properly either. I contemplated using a soldering iron to warm the surfaces up a bit and then get them to melt together, but the potential disasters in that plan kept me from it.
