I’m a real newbie and I have a project coming up to fabricate a small trenching bucket for a mini excavator that will require bending 3/8” plate mild steel for the back of the bucket. The plate only needs to be about 6” wide, but in the future I want larger capacity. I don’t own a slip roller yet, but most of them have a listed capacity of 16 gauge anyway. What should I be looking for to bend heavier gauge mild steel?
