    Tapping fine over coarse threads

    I mistakenly had a hole tapped 4-40 instead of 4-48. Normally this wouldn't be the end of the world. However, ball spring plunger only come in 4-48 in that size. Is there a remedy to this? I've attempted using a helical insert but the material is titanium and it just tore up the tap.

    Profile tolerance for an array of slots

    I have an array of slots that are defined by basic dimensions (Radius, length) and a profile tolerance. I would like to dimension and tolerance the pattern but am not sure how. If it was a hole pattern I could write 300X .25+-.004 with the attached positional tolerances and basic dimensions...
