No realy way round it mate.
one thing you can do it start a seperate thread for each bit you do to your motor and then link back to your main thread.
as a sort of a index with a breath text about it, a pic or two highlighting what its about and then a link to the main thread it self.
You would have 1 post per page, as it were cause you can't edit the top post to add more threads to it.
I hope that makes sense.
