Then we need to hem the flange so the bottom isn't quite so sharp..









A 1/2 x 1/2 aluminum angle is used as a height gauge so we can use the roloc sander to get our flange to a consistent height. This will allow us to use a tipping die in the bead roller to fold the hem..








To start the fold of our bottom hem the Fasti bead roller is put to use.. We selected a bottom die that would also serve as a backstop. Using a regular step die results in dragging/interference as soon as the panel starts to lay over, so we opt for a large bead die instead. The rounded "corners" play more nicely with the panel as it travels across the die..

Then the part is re-installed in the hammer form to hammer the hem flat..
