PVC is not exactly a great structural material. It softens and deforms 
at fairly low temperatures.

Why not buy a piece of Garolite from McMaster Carr...

Runs about $11-15/ft for the brown stuff, $23/ft for the G-10/FR4 stuff

Probably be on your doorstep a couple days after you order it.

Search for plastic rod, then answer the questions about diameter and 
material..

Acetal (Delrin) might also be a decent choice.. About $6/ft.  Machines 
nicely, quite strong.


You can also get pultruded/extruded fiberglass tubing, but I don't think 
1-1/8" is a standard size.

Garolite tubing is available in that size.. $24.21 for a 40" length..
