And the Can of Worms has been opened!
(What a way to hijack a thread, I plead guilty!)

So far we have:

• I would guess welded with fire and brass.
• Square C.I. rods…
• I've used nirod before.
• mild steel jobber electrodes with a copper wire wrapped around them.
• -Cast-Iron/RCI
• Machinable nickel rod
• Eutectic Weld Electrodes for cast iron (castolin)
