Burnishing tool

[t-jacobs]

I have heard rumors of a home made oil pump burnishing tool. Does anyone know how to make one and how to use it?

[t-jacobs]

Is anybody out there?

Are you talking about lapping the check ball seats?

Steve LeMay of Resurrection Cycle Works made the two that I have.

Steve's burnisher's are professional quality.

Attached is the first one I cobbled last decade (piloted stone is for pre-dressing damaged seats).
Anyone with a lathe and silversolder can whip one up
