Airdevil,

I agree with everything that Kevin said - good advice.

He mentioned that when the glue is on the parts they tend to slide around. This is how I solve that problem....

Place the first piece down on your building board. Then place pins all the way around this piece. The pins go into the building board, not the part. What you are trying to do is surround the first piece with pins to hold it in place. Now the pins surrounding the first piece will act to guide the second piece into perfect position.

I hope this helps.
