I melded together a 1.25mm pitch cog with a 0.95mm one with only about
..2mm ecentricity but much the same result.
I've now noticed why pre-selecting track 2 or 5 or whatever results in
no play. The sledge is propelled to the periphery as though track 10 was
selected, so something wrong in the interpretation of "0" track data ?
or something beyond any resolution by me unless anyone has any insight?
