I apologize for my ignorance since I don't own a 29-1 but most of the sheave and axle arrangments I've worked on did not require removal of the mast cap. The arrangement I've seen has the axle (a smooth and straight stainless rod) pass completely through the mast and kept in place on both sides by a stainless steel plate. The plate that covers the axle hole is held into the mast with a single screw.
As for skipping off the sheave it sounds like the sheave box is too wide or needs a divider guide. You are on the right track though because the sheaves should be matched to the type and diameter of halyard.
