I have a BPI 8ga roll crumper as well as a 16 & a 20. All of them have one major flaw, in my estimation. The outside radius isn’t. It’s a sharp 90 degree edge, but the inside radius is nice.
I have a deluxe Bridgeport Products roll crimper in 12 ga and I would love to find that same device in other gauges. It has 4 roll bars as opposed to BPIs one.
