I searched but couldn't find anything. This must have come up before so forgive me. Lamp fixtures apparently use a straight pipe thread. I have looked in some of my machinist books (I'm an amateur homeshop guy) and can't find much. I want to drill and tap a hole for a lamp fixture nipple. The nipple is about 0.386 inches in diameter measuring across the tops of the threads.
At my local Ace HW they show the designation for these nipples as 1/8 IPS. I believe the TPI is 27. Does the IPS stand for Iron Pipe Straight? I'm not familiar with pipe thread designations and can't figure out the 1/8 either. What on earth does this stand for?
Do I want to buy a 1/8 NPS tap to tap this guy and therefore a tap drill "S"?
Thanks in advance.
