Bending an alu hoop is no problem either, then gluing and glassing the ends together. Make a small section to fit to the spi-pole and it's ready. If you really want to make it well, route a groove for the snuffer bag, or blind-rivet it to the hoop. I did it in my basement in an evening after an idea Phill expressed. I was concerned about the glueing and glass for the pole mount, but it have held up well for several years now. Outperforms most of the commercial carbon snuffers..
