Lol, The Duro-wal wire outfit with their zinc coating tank left along time ago here. Helped dad do some "hot-dip" galvanize production over a couple weekends in my HS days. Whats the cost on a brick of zinc these days?
Not rare , just an old CH4B I wanted to use short term as cheap as I can.
Looks like that's there on purpose, not sure for why.
That would be best, and slicing the bottom would easy enough. The I could see any crack I guess.
