I just finished our new steamer for the Alaska Kodiak and it really works great. Being a certified member of the overdoers ananymous club, I was tired of the big copper urn of water on the hopper lid as its a pita to lift,set down,lift,put back, each day twice a day when filling the stove. It held 2 gallons of water and i fed it 2 qts,twice a day.
I took exact measurements and pondered a tank fabrication for a year now and last week put steel to chop saw and made it.
Didnt weigh it yet but can say its about 50-60 lbs
. I used 1/2" cold rolled steel 4" wide and welded it to 3/16 sheet. The Hyper-Therm 85 made short work of the sheet and the Evolution Rage cut the 1/2" thick stuff nice and square. Triple multi-pass welding got it water tight and Rutland hi temp black and a cheap brush gave her a protective coat. It holds 3 gallon and a qt of water and the prop rod nut keeps the lid open at such a angle so as to allow a large amount of wetted surface to impart steamy H2O to be moved into the house via the factory dual cage speed adjustable fan.
