Got a I suspect new-ish Lodge cast iron skillet with a small void, maybe
1/16" in diamter. What's the laziest way to fill this in? I'm thinking
about just peening in some soft steel wire or copper in there to just plug
it. burned up oil will coat in in the end. Have access to an oxyacetylene
torch and pickup any sort of rod being sold. Not really sure what type of
cast iron us used in these. It makes black dust if you grind it and it
takes as while to get all the dust off.
