Restoring & re-bushing a classic mini primary gear - Part 2

This is how I do it, other may have different ways of achieving the same outcome.

What’s the reason behind not boring both bushes together in the same pass? Is it just because you can’t with 1275 primaries and you use the same approach as those, or is there a technical reason?

[@ACDodd]

Two different materials load the boring bar differently when cuttting and the sizes change between bushes. Secondly it wastes time winding the tool all the way through the gear every pass of the tool.
