    Excuse my typo, I meant 0.005mm not 0.05mm but regardless, the proof is in the pudding. If it grinds well, then it works, just no guarantees for the longevity.

    Spend an after noon with a depth mic and select each feed at a time while rotating the spindle exactly one turn. Then mark our what combination does what. Should give you pretty good results.

    EDM will be the lowest risk option. Put it this way, if you break the tap, youíll only need to EDM it anyway. So save the hassle and EDM!

    Whatís the companies hourly rate? Jobbing shops that could handle an open tolerance job charge maybe around £40 an hour? Correct me if Iím wrong.
