I am looking to buy a box and pan finger brake, but most of them are 16 gauge mild steel rated. I'm going to be bending 16 gauge 304 stainless. The thing is, I'm only bending maximum 13 inches long. The brakes mostly come in 24" length @ 16 gauge. Will I be able to bend the 13 inch stainless since it's shorter than the full length? Are the fingers normally hardened on these machines? I'm wondering if the sharp edge will dent if I try the stainless. Thanks
