Looking for two pieces of nesting pipe

Hello, I’m building a knife maker’s vise. I need two pieces of pipe, about 12 inches long; the smaller pipe should fit smoothly inside the larger pipe. The inside diameter of the smaller pipe should be at least 2 inches. The pipe walls need to be thick enough to weld a nut onto.

Here’s a picture of what I’m trying to make:

If you have enough for two, and want me to make you one as well, I would be willing to do that in exchange for the materials…
