I'm wondering about making a simple device for holding blanks with adjustable and repeatable eccentricity. Consider cutting a 2 in. length of 4 in. diameter steel or aluminum bar into two halves at an angle like a large set of wobble washers used in cutting dados. One half to be a faceplate with an angled face. The other half to hold the blank as a rotatable faceplate ring.
Armchair machining is confusing, so would some engineer-turner or maybe somebody who uses wobble washers please explain, so I don't waste time.
As the angle-faced ring is rotated on the angle-faced faceplate, does the angle of a blank fixed to the ring increase from in-line (axial) to maximum at 90 deg. then back to axial with further rotation? IOW, does
90 deg. provide all the adjustable eccentricity I can expect? Will this work? Has some turner already tried and used it? Who? Where? Why? TIA, ArchFortiter,
