Can pipe threads be cut on a lathe with a taper attachment?

Correction:(Note that when you cut 11 1/2 TPI, you will need to engage the threading dial on the same number.)
Are the "metric" smaller pipe threads the old British Standard series?JRW
another way to do it with out the taper at. is to rough cut it staight leaving oversize then finish with a die.
Many lathes cannot cut the smaller pipe threads such as the 1/8"-27. Most will cut 28 TPI. I leave my taper attachment set for 3/4"/ft and take a ight cut with the taper attachment before cutting the thread. Are the "metric" smaller pipe threads the old British Standard series?

.... Be prepared to withdraw the threading tool with the cross-feed handwheel at the end of the thread.

Correction:
For half threads, egage when the thread dial is on an odd number, or a half turn of the dial.
For 1/4 threads, engage on the same number.
