Why?? A suspended wire vertical would be a lot smaller than 1/8 inch
and would work just fine.

Is the need for 1/4” tubing for 40 meter verticals?
I cannot imagine making a 40m vertical or any other HF vertical or half wavelength
element that would have anything smaller than 3/8” tubing at the tip.

I wasn't worried about stiffness.
It is the telescoping to the 1/8" rod. the 0.049, it was pretty tough to get a
good grip to lock the rod in place too much slop.

That's where I have been buying aluminum tubing. They don't have 0.058"
wall thickness in 1/4" diameter tubing, but the closest they have for that
diameter is 0.049", which I suspect will work.
You don't get a whole lot of extra stiffness by going from a .049 to .058 inch
wall thickness in tubing this small.
