    Buttress Thread Help Measuring

    Likely all true, but we both know better than to assume anything. The oddball diameters and designations might well be accompanied by other "special" features.

    Buttress Thread Help Measuring

    6-3/4"-3N Buttress-2ASA, RH I haven't seen 3N or 2ASA on a blueprint before, and can't find them in the standard or by using Google. If it was my job, I'd be on the phone to the customer. It could even have a modified thread form.

    Turning RPM calculated from Turn Diameter or Stock Diameter?

    So, when facing from large diameter to small, you use the tooltip to calculate RPM, but when turning along Z you use the stock diameter? Could get confusing.

    Turning RPM calculated from Turn Diameter or Stock Diameter?

    If RPM were to be calculated using stock diameter instead of turn diameter, then what would be the reason for having G96 constant surface speed? My vote is for calculating RPM based on the actual diameter being turned.

    Back up your computer!

    I use Terabyte's Bootit Bare Metal to make a complete image of my Windows partition every week or two. I include the date in the name of the image folder (ex. 121517.img for December 15, 2017). I also do an incremental backup (not imaged) of the partition where I store data. I save the image...

    Custom thread size?

    You should designate it as 1.4130-28 UNS. You would then have to include on your drawing every dimension needed for machining and inspection. According to the H28 manual, this would fall into the category of “threads of special diameters, pitches, and lengths of engagement”.
