The cotan scale goes through two cycles so that you do not run off the edge of the scale as commonly happens with slide rules. gl -------------------------------------------- On Mon, 6/16/14, Hanno Ixwrote: Subject: [NavList] Re: Flat Bygrave alternative configuration To: garylapook@pacbell.net Date: Monday, June 16, 2014, 12:41 PM HI, Robin:Please remind me why your alternate scales are of different width?Since the scales are slanted I suppose they are meantto create helixes ( 'helices'? ) on on cylinders with different diameters, right?This would be one explanation.�I would like to use them in G.Pook's "flat" mode.The slant is not much of a problem - a little annoying, though.However, the underlying log() scale on which the scales are based must strictlybe of the same scale for my purpose, no?Am I missing something here?�Hanno�� View and reply to this message
