Dont forget to use soft wire or anneal your stock before doing this!
If the wire is too this for thick for bending, use the rawhide mattle. Strike the metal next to the mandrel-not on it. Tap the wire around the mandrel. Its best to have the mandrel in a bench vise, but it works if you prop your mardrel against something sturdy. Just be careful about leaving knicks in it, i always cushion mine with a rag.
