[HBR] IF's winding

[Brian Ford]

  I'm finishing up my Hb coil master,  Ater a fruitless search of a pics of a Morris, ( with some item in the pic to get measurements,)  and to cheap to buy the gingery book,  I guessed at the dimemsions,  I used friction drive while i do some study on gears. 

But to the point,  I want to try to wind some If's, has anyone done this?  or perhaps know of a ready soure of info?  My older handbooks are Berift of any info of this depth. 

Keith.
