Fancy way of saying lets make changes and use up spare bits kicking around.
The contact wheel mount was the first and easiest change from the flat platen only next was the small wheel attachment that I made two sided.
Second side is for an adjustable blade holder for shaping curved edge blades.
Holder laid down in loading position Beveled the nut for full motion of joint
Scavenged most of this build including the spare blade holder for a knife sharpening kit. Still have to make a fixed holder for grinding straight blades or sharpening.
