I need a "T" made out of two six inch 1/8" wall thickness pipes.

I need a way to mark a chalk line on each pipe so I can cut it with a
torch
and then fit the two together and weld.

I did a layout like this in drafting class thirty years ago. Made each
piece
out of paper. Cut them out and wrapped around the pipe to mark the
lines.
I
don't remember much else about it.

Anyone know how this is done?

Go to a welding store and buy a "Wrap Around". There are different sizes.
There are instructions and marks on it that allow you to cut out the
desired
shape you need to get a repeatable pattern. I believe you can even order
one specific to your use from them.

A wraparound won't give you the ordinals to cut a branch.
