Hi MockV-
Here's a small list of the things I use most when building:

-CA, thin, medium and thick
-CA Accelerator
-Razor saw
-PLENTY of razor blades or xacto blades, whatever your pleasure
-Wax paper to protect the plans
-Toothpicks for getting glue to hard to reach places
-Q-Tips for getting glue out of hard to reach places
-Sandpaper, like you said, I use 100, 200 and 400 grits
-T Pins for holding parts in place
-30 Minute epoxy - I find this is strong enough for everything but cures fast enough so that your whole night of building isn't over when you use it.
-Top-Flite Iron and Heat gun like you said
-Paper towels for wiping sawdust, etc. etc.
I feel like I'm forgetting a few things, possibly many things, but hopefully this will get the ball rolling.
Enjoy!

Reid
