sizes of the coil

["J. Kooiman" <jkooi-at-wish-dot-net> (by way of Terry Fritz <twftesla-at-uswest-dot-net>)]

Hi all,
 
are there standard sizes or dimentions to be used best for a TC.
 
with this I mean like :
 
space between primary windings
space between primary and secondary
ratio between primary and secondary
ratio of the secondary in with and length
size of tank cap with secondary/primary size
turoid size to secondary size
 
 
I would really appreciate it if all questions could be awnserd, than they could
also be put on my beginners page.
 
greetings and thanks in advance
