Abstract
A cradle for a hand-held tool for machining of cylinder head valve guide holes. The tooling has a pilot portion. A collar has a passage for the tooling and is shaped to engage a least worn portion of a valve seat associated with the valve guide hole around the circumference thereof without engaging more worn portions of the valve seat. The cradle comprises a bracket which has a passage for the tooling without passage of the collar so that the bracket can bear on the collar. Force is applied to the bracket to hold the collar in engagement with the valve seat.
