I’m hoping someone can help answer a question I’ve had a hard time finding an answer to, and that’s: Why are air coils almost exclusively cylindrical?
Are cylindrical forms more efficient than say… a square/rectilinear coil form? Or a hexagonal?
It seems the only exception to the cylindrical coil form is the texas bug catcher, which is octagonal.
With the tools in my shop (mill; no lathe), it would be a lot easier to work with non-cylindrical forms. But, does that throw the Q out the window?
Thanks and 73
