TK 1636 does a great video series on a complete build you can see him size up for shims in this video

or I would go through UKSWRATH build here a follow how he creates the joints on all of the limbs with cover strips on the inside first to give it a solid butt jounint.

How does anyone with a PVC kit add a seamless shim?
