Just to give you an idea of the size of coils i am contemplating.

These measurements are taken in relation to the diagram, assuming the diagram is drawn to size

If i used a 2 Inch Core

iron core diameter = 50mm = 1.96 inches

length core = 1311mm = 51.61 Inches

secondary outer diameter = 252.5mm = 9.94 Inches

secondary circumference = 793.25mm = 31.23 Inches

primary outer diameter = 158mm = 6.22 Inches

primary circumference = 496.37mm = 19.54 Inches

length secondary = 1022mm = 40.23 Inches

length primary =1152.5mm = 45.37 Inches

primary wire 30awg diameter = 0.255mm

secondary wire 16awg diameter = 1.291mm

primary Turns = 4519.6

secondary turns = 791.63

primary wire length = 392841.38mm = 1288.85 feet per layer (1)

secondary wire length = 627960.50mm = 2060.23 feet per layer

If i used a 24 Inch long core

Iron Core diameter =23.5mm = 0.925 Inches

length of core = 610mm = 24 Inches

secondary outer diameter = 117mm = 4.6 Inches

secondary circumference = 367.57mm = 14.47 Inches

primary outer diameter = 73.5mm = 2.89 Inches

primary circumference = 230.91mm = 9.09 Inches

length secondary = 465mm = 18.31 Inches

length primary = 536mm = 21.1 Inches

primary wire 30awg diameter = 0.255mm

secondary wire 16awg diameter = 1.291mm

primary Turns = 2101.96

secondary turns = 360.19

primary wire length = 485363.58mm = 1592.40 Feet per layer (1)

secondary wire length = 132395.04mm = 434.36 Feet per layer
