Primary tubing size



Original poster: "Mike Knowlton" <amdx@xxxxxxxxxxx>

I'm planning the primary for my 8-1/2" x 40" secondary.

I think I'll make the primary a sloped pancake @ 25*,
Any better suggestions?

I'm considering 3/8" over 1/4" copper tubing.
Any good reason to use the larger diameter?
Turn spacing provided by 10-32 nylon screws.

Also how for should I start the inner turn from the
O.D of the secondary?

        Thanks for the feedback
