cut a track in the eccentric with raised edges. The strap would ride in this groove with shoulders cut to allow it to sit down on the track.

The strap would ride in this groove with shoulders cut to allow it to sit down on the track.I'm not sure I understand. What is meant by 'shoulders'? Wouldn't the strap ride in the groove and be held by the raised edges?Is it because the thickness of the strap is the same (or thicker) than the groove plus the width of the two edges?Or is the thickness of the strap equal to the width of the eccentric groove?Not that I have a whole lot of experience but I do it the way Chris mentioned. And I drill/ream for the main crank then offset for turning/drilling/reaming the eccentric. All done on 4-jaw.
