For example, a 2.0000" shaft with an eccentric journal of 1.2500" with 1.0000" of throw would require a minimum of 2.6250" plus allowance. This would require some prep work to establish centers to turn offset twice, if starting with a min sized bar. Smaller offsets, and/or shorter work can be done in a four jaw, as recommended.
