A tool slide assembly mounted on a clamshell lathe where the clamshell lathe is used to machine an out-of-round work piece. The tool slide assembly generally comprises a base mounted on the rotatable ring of the clamshell lathe and a tool bit holder. The tool bit holder comprises a follower member and a tool block adapted to hold a tool bit, where the follower member is urged against an outer surface of the out-of-round work piece by a plurality of springs. The tool block is incrementally translated such that the tool bit gets fed into the out-of-round work piece.
