I can see the same basic (building technique) questions are asked again and again -
here in this topic most of them have allready been answered by me -
and also explained with lots of pics! - The FAQs, so to say.

As it is very long - which lots of unspecific stuff in between - look out for the "IDEALIST" -
especially pages 2,5,9,11,14! -

I hope this helps.
