I need several hundred 2 1/2" ID rings rolled from 1/4" bar stock both sq and round. I didn't want to pay a buck + each for them either. So i took my powered scroller base and motor and replaced the scroll die with a round die the size i want for the ring. Now i can do 30 rings a minute like a big spring then just clip them apart. Just feed in 5' bars. Will get some pics...Bob
