Re: [TCML] Making a neat primary

["Phillip Slawinski" <pslawinski@xxxxxxxxx>]

was laid in the grooves it would form a perfect archimedean spiral.
Previously I zip tied the primary to a piece of cardboard [not recommended]

If you're interested I can send you the drawings for the pieces I used for
my primary supports.
