Ah, once again back to this topic for more questions!
I have been considering having a crack at making my own track and points. I have found Greenwood Model Railway Products who appear to offer beginner-friendly point kits. However (and this isn't the first time this question has been elicited from me), I have noticed that there is a choice of "type" which comes down to radius selections etc. I honestly have absolutely no idea about what these mean and I can't seem to find any simple guides or explanations for these random numbers and letters. Could anybody explain the notations for turnout radii in plain English for me?
In other words, wold it be possible to explain the difference between A4.5, A5, A5.5, A6, B6, B6.6, B7 and B8?
