I tried for along time to get the penny stove to simmer the idea is that it cools the stove down because the jets heat the outer rim of the can and the alcohol.

My solution was to actually make two Jim wood cat stoves one that would burn hot to boil water and the other low and slow to simmer!

I've had great success with this set up and the only tool needed to make these stoves is a decent hole punch!
