Help: Coil Housing Dimensions..

Big metal is negative here. But for to correct final zero or when zero was moved from original or fo to obtain better zero, you can use head of screws glued in the coil housing for to correct it, or directly the entire screw glued in vertical position. Can be some hardzarous! And there is more. You must try the kind of screw, based on iron, bronze or bronze-iron, etc. Do you see why is hardzarous?

Better know where wires are before screwing...... I always say.

I have shielded the bottom side of the coil with graphite now (see below). Before sealing the coil totally, I will investigate the phase shift adjustment on real field tests. If the balance winding is not shielded, it will give false signals due to capacitive effects. I have tested the unshielded balance winding with my hands and it is giving some signal.

Tomorrow is the big day.

I made an universal coil holder for some quick and dirty coil field tests. I was quite surprised about the materials: polyester resin is solving polystyrene!!! (see below)
Anyway, the coil holder is not perfect but will do his job well. I will make some easy coils next time using only polystyrene and hot glue. The coil holder will hold the test coil.
