Sounds like you have a real mess! :-o The only way to get a nice neat
primary is to start with a well designed and supportive primary form. I
flat spiral is relatively easy to wind, though time consuming. You need
to make four (or more!) strips of wood or 3/8" plexiglass to hold the
wire/pipe. Below is an example of what they might look like- the "O"
marks represent drill holes where the wire/tube would pass through.
These four strips would be arranged radially 90 degrees apart (second
diagram), and notice that the hole spacing allows for the wire to spiral
outward:

After these strips are glued down to a base platform, all you have to do
is start inching the wire through the holes (easiest to start from the
outside) until it reaches the center. This takes A WHILE!!! Be patient
and if you get frustrated, go and do something else for a while.
Hope this helps,
