Hello all, I am looking for a little assistance on creating an 11 1/2" NPT on the O.D. of my part. I for some reason cannot get it to thread how I need it to, that is when i'm not getting an error on my machine.

Any help would be greatly appreciated,

Thanks.
 
Lathe or mill?

Lathe has always taken a bit of screwing around to get correct, the help documentation if you search under NPT is actually helpful and offers two ways of doing it and IIRC has a table for the dimensions needed.

For milling go to
Plug-ins>Geometry>Create tapered thread and select your thread from the table. Then just use a regular contour operation or two to cut your thread.
