Stew,
Make up a bronze fitting for either end, with a goodly amount of strength in it, then silver solder say a piece of 1/8" tube between the two. That should be a lot stronger than actually threading the pipe itself.
See C-o-C.
Or you can come around and root thru what pipe I do have. I think I have some 4mm stainless, but it is only thin wall, also, I think I have some 3/32" thick wall, But you would have to root thru my stocks to find it.
