Hi
The core diameter for a 1 1/2" BSPP thread is 1.7656", according to two old books I have. If you need any other data just let me know. I have a table which goes up to 18" BSPP which I could scan for you.
I thought about putting it on my website once, but never got round to it.

Wouldn't mind that as well, maybe it will just sit in the collection of old data, as I currently use up to 3" on the farm, but it may be needed one day... What about the drill sizes for 3/4"BSP and 1"BSP?

Here's the best table of BSPP data I have:

It's from "Fowler's Mechanics' and Machinists' Pocket Book 1942". Some of the numbers are a bit fuzzy, but you should be able to figure out what they are. If not let me know and I'll check the original.
Best wishes,
Chris
