I see Rusty Wood has come to your rescue.
That being said, the automotive section at Canadian Tire has small fibreglass kits that will last the rest of your life
One of my favorite bedding pillar materials is made from Aluminum/Titanium Arrow shafts, which come in different diameters.
Any archery shop or gun shop that sells the arrows and cuts them to custom length for customers, will have a box full of the left over shaft ends.
They're very easily cut to the lengths needed and a hand drill with a file will trim the ends perfectly.
Just a bit of info for the next job.
