For those residing in Oz, The Visypack plant in Brisbane produces a
food-grade 60 litre stainless steel drum. The version that I was
interested in was described as having a "full open lid", retained with a
clamp and nitrile (alcohol impervious) gasket. While I haven't seen one
in the flesh, it sounds ideal for a boiler.
At the time I made enquiries (Dec '02), Visypack's address was: Oxford
St, Bulimda, but they were soon to shift to: 40 Ingham Place, Hammett.
The contact person is a Jim Klaer (pronounced "clear"),
Phone no. in Brisbane: 3890 9777. Price: Aus$154.66.
For those (like me) residing in NZ, my original enquiries were through
Visypack NZ, but with freight etc. the price became prohibitive. At this
stage, I'm waiting for someone flying to Brisbane to bring me one back
as unaccompanied baggage!
