Hi Alan,
I've looked at many video's that are up on Youtube and everyone of them I could easily pick mistakes in, even some of our own video's are no longer quite relevant as they have holes in them that should be corrected by today's standards, but in saying that one has to just be able to take the good bits out of them and disregard the bad bits. It all comes down to experience I always say. You'll discover all this quickly.
My best advise is to motor around some of the Model 45 videos and get a generalised feel for what you've got in comparison to what they are showing and if there's something in particular you're not quite sure about you can always ask here as we won't lie to you due to any contractual arrangements we've got we've got with certain commercial ventures, as we have none of those.
Cheers,
BB.
