Boiler stand, gas fire, and firedoor latch/catch.
The boiler will most often be fired on gas, but it is being made so that it can also use coal-wood.
So the base needs to cope with ash from coal or wood, and also have adequate clearance to fit a gas (propane) burner. And to look OK. And to be not too heavy to carry.
This is what I have come up with.
So I increased the jet diameter……
The flame size increased, but the mix did not improve. A work in progress. Another jet change, and an adjustable regulator to be tried next.
To do something positive, I made a firedoor latch and catch. Some CNC and filing.
