Shame on PB school board. That is a real violation of 1st amendment rights. You might think they were guilty or had a thin skin.

Speaking of serpertine belts. I suspect they are J size poly-V
and belts are not very expensive. Use the lathe to cut the grooves.... 40 degree. Kennametal lathe book has the specs.
Belts are usually under 10 $$. Good energy transfer.
My lathe ( Jet ) expects 2:1 from motor to spindle drive.
