V cut buttom will work, but will increase manufacturing cost.
I am thinking to make full Kettle with my basket and power draft.
It will be a big project because that most people do not trust my design.
Indeed my UDS or PBC design with ash box and fire basket works great.
I am using it a couple of times for my self.
But none shows interest in my UDS or fire basket.
UDS is so popular, I guess that most do not think there is any free room to play with.
My big puzzle must be name of "made in China"
