Yes, this is exactly what we did. Heat one end of a small (~6") hex shaft -- the other end in a vice. Get it hot and then just push the PVC tube onto the hot hex shaft.

Worked great for us.

Note. It is the size Schedule 80 that has a hole of a little bigger than 1/2"

That is the beautiful thing about Schedule 80 (rather than Schedule 40 available at Home Depot, Lowes, ...): you can get them in sizes with IDs just a hair bigger than 1/4", 3/8", & 1/2". That makes the perfect for making spacers for 1/4", 3/8", & 1/2" shafts.

FWIW.
