I tried turning one of those resin blocks into a round box. After about 2.5 hours I got it to this state:
I think the most useful part is the waste looked like confetti, so if anyone needs a confetti generator, we should just pop it on the lathe.
If anyone wants this to throw an LED inside, feel free; it might make a cool lamp. Otherwise, I’m done with that resin, was way too hard turning an a wood lathe, it caught too readily, I suspect a metal lathe would be more appropriate for the material.
