Flying Engine Mount Build Part 2, DIY Centering Rings
Initially the center hole will look rough.
Slip in a BT-5 and shave off any raised edges. Don't take off much, you'll still want a tight friction fit around the BT-5.
It's easier to separate the rings before cutting the outside circle.
The outside circle can be cut with strong, sharp scissors.
Stack the rings and knock off any high spots with 220 grit on a block.
To seal the edges run a bead of white glue around the outside of the rings. Use white glue for visible glue lines, it'll dry clear. Yellow glue dries yellow.
