Any ideas on how to wind this PI coil ?

I like the bevelled edge thanks

Perhaps use a centre disc former with one beveled edge to start the coil off and dabs of sg as you go to hold in place should not be too painful as only 20 turns please keep us updated with your progress and any tips you develop!

The graphite is for sea water.

I have been pondering the construction of this PI coil for some time, does anybody have any ideas on how to wind it to get the slight offset , I have been considering winding between two flat plates with a spacer slightly thinner than the width of two wires, and starting with a single wind of string to get the offset, any bright ideas ?

Why the graphite ? with 24awg wire, shielding is not be needed unless your hunting where there is lots of wifi routers and lots of electrical interference, but if your like myself, hunting in urban area's with a Surf PI, you end up digging more nails then treasure's .

Thanks Gary, I have worked out the approx inner Dia, I had not thought of winding in reverse , I will have to try and picture it in my mind for a while to work out how to do that mechanically.

First you would need to determine the Inner Diameter.

It would be easier to wind it reversed, going from the Outside to the Inside.
Using Crazy Glue to hold it.

I think the End result would be the same.
