RE: CA hinges
Another thing that can help a lot (if you aren't already using them) are CA applicator tips. They let you dispense a lot smaller drop of CA at a time, as well as being able to place the tip exactly where you want the CA to go. You can find them at Tower here: [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXL490&P=7]CA Applicator Tips[/link] . You might also want to check at your LHS for them. Most places that sell CA should have them.
Hope this helps
