I know you can get a ruler anywhere, the problem is at the moment I have exactly $0.00 to my name (well, i have a box of pennies, but no...). I figured it out anyway, there is a place in the book that shows the sizes, so I can compare it to that, compare it to the plan and know that its the right one.
The CA didn't exactly squirt out the sides, it either got pushed out and leaked out the side or I accidentally put a little bit on the side, either way I ended up doing the same thing tonight trying to get the wings right, and I almost glued an extra piece of balsa that I was using to line a few other pieces up. For the most part I've found I can put a piece of duct tape on the board and just lock the part down with T-pins, the duct tape does a good job of keeping the pins from going up too much. I'm also using medium CA, thats what the instructions recommend, and from what i've seen it can kinda fill real small gaps.

MasterSmasher: No garage sales around here, the past two days the high has been about 30, nobody has garage sales this time of year lol. Will find containers though, for now my pretty quick and crappily made styrofoam shelf is working all right.
