Exactly. It turned out to be a glitch.

Anyway, I am exactly the same when it comes to building stuff. I like to get the pieces where I like it, and hope it works but my living space won't allow it, so I just do that on a much smaller scale.

I just happened to have some books and free time, so I wrote the program on my calculator.

Its not as complicated as it sounds. All it does is asks you for the weight, angle, angle etc. and it punches the numbers in an equation on its own and gives you numbers back, which you have to figure out.
