Help with American terminology in Build your own Telescope

IN Roger Berry's book, I'm looking at what parts I need for my 4" reflector.
I'm somewhat confused by his terminology, in particular, what is a

12" nipple

and a 1.5" short or close nipple

Personally I would refer to a 1.5 inch nipple as being pretty long, and as
for 12", well taht doesn't bear thinking about !

And what;s a box of 3/4 " wire brads ?

Here is a page with a picture of a brad nail:

Not sure about the nipple since I don't know what context it is being used
in.

Basically its describing part of the stand for the telescope.

There is a 1.5 diameter,12 inch pipe, at the end of which is screwed
on a t piece, which has threads at all 3 ends.

From what I can make out the 12 inch pipe is the nipple. The short 1.5
inch nipples are short threaded pipes that screw into the t-piece at
one and and flloor flanges at the other end.

So is a nipple just a threaded pipe ?

Just been looking at pages 57 & 58 and that looks so. Good luck with your
scope.

I've jsut had to spend a good hour finding an imperial to metric
conversion chart, and converting all the screw, nut and bolt sizes
too. Joy of joy, better be worth it lol !

ANy idea where I can get the 1.5" nipple pipes from ?

I'm somewhat confused by his terminology,

"Nipple" is Merkinese for "a bit of pipe with a screw thread on both
ends"

"Brad" is another word for a nail-without-much-of-a-head. A wire brad is
therefore what we would call a "panel pin". (Brads over here usually
refers to cut nails, such as flooring brads -- these are cut from metal
plate, as opposed to being made from wire)

Best,
Stephen
