Luckily no fatalities or injured from what I've read.
Not sure but I think I've read the cause was electrical equipment failing.

Doesn't the comp just stick to the drum then??
Sorry, but I can hardly imagine this is a good method. I think pressing wet comp through a screen above the drum is better for making coreless stars...

I still haven't finished my starroller but what I have in stock to use as cores is rapeseed.
Very small round balls, ideal for cores!
