besides all the great advice you have gotten so far i will offer just a bit more that has saved me much trouble in the past. first and formost if you feel yourself getting frustrated....you are. step back let it be for a day and come back tomorrow in a clear frame of mind. second bit of advice is that if your building it and it doesnt seem right....its probley not. read the distructions...i mean instructions look at the perty pictures and think about it awhile before you break out the glue.
