Out and about at a sawyers buying more stock i was reminded of the slender old water tank in Rollins book ( i think , well at least some book i read) when i saw this in the snow. Free for the taking, its an old water tank with super heavy galvanizing. Many years outside in a field and not a sign of rust. Was a fuel tank at some time for a boat, once the top is cut off i'm gonna try boiling my stem stock. Usually soak them for days then steam, i'll see if this makes a difference.
