Been mostly at around 4-6 oz.
Read the cat tin fosters post somewhere on the web about where someone used a large cat food can top on a fosters can to make a strait walled can.
Works on the outside and is fairly tight. Tuna can works on the inside.
The lid is the bottom of the cat food can.
Something nice about this setup is the top wont accidentally slip off but if you tug on it it will come apart so you can clean both parts.
The stove weighs 7 grams and is one of my favorites to date. Small red bull can.
Jets fire off in about 5 seconds and it boils a cup of h20 in 3.5-4 minutes with 3/8 oz of DN.
2 cups in about 6 minutes.
The Tape on the loop and lid are what is called silicone rescue tape and it bonds to itself. Ace sells it.
The wire is just SS wire I got from the hardware store.
The green top is from an almond can.
This rig put into a tang container to make it crush proof adds another 1.8 oz or 3.8 oz total.
