The court held that this violation of Rule 43 was harmless error. In Phillips v. United States, 533 F.2d 369 (8th Cir.), cert. denied, 429 U.S. 924, 97 S.Ct. 324, 50 L.Ed.2d 292 (1976), the court was also faced with a claim that a defendant should have his conviction reversed on the basis that he was absent during the period in which challenges were made.

An appellant can make a claim of ineffective assistance of counsel only by specifying particular errors of trial counsel, not founded on mere inexperience, lack of time to prepare, gravity of the charges, complexity of defenses, or accessibility of witnesses to counsel.
