Yours is a good description of the process you use, I'll probably use it or similar helping folk make sharp bends. 

This was a good example of why I tend to try to get everybody using the same terms and names. It's not because I know what they are it's just so much easier to communicate when everybody uses the same jargon. 

Frosty The Lucky.

My main business  is polished bronze pipe.

I have a monster bench vise, a Charles Parker Trogan 727. 

I polished the jaws because  I use it for the same thing all the time.

For other vises I have made jaws from aluminum angle, plate and copper flashing.
