I just finished flattening some 1"x1" 16g pieces but I forgot my camera is at my office.
You may want to pick up a 5lb Sledge Hammer.
1- In the Vise with Mapp torch heat- needed cheater bar
1- Flattened with 5lb sledge and Mapp Torch for heat
1- Flattened with 5lb sledge NO heat- just needed a couple more hits with the hammer but worked easily enough.
1/2" 16g should be a piece of cake.
I'll post pics tomorrow.
