Very neat link - thank you.  I was going to suggest approximating a parabola with a very eccentric ellipse.  You can use just a string to make an ellipse so it requires very little in the way of equpiment.

Adding in a t-square is no great burden and using it in the way suggested on that website looks easy and accurate - no approximations.  I like it.
