Request: Step-by-Step guide to make a HHO blowtorch?
Can someone please make an "Idiots illustrated step-by-step guide to making/ and safely using a HHO blowtorch."
I am into metal sculpting, and I'd rather use HHO, than some explosive gas (methane/butane) in my house.
Proven tech, or not. Regardless of how "inefficient" it may be - I'd like to be able to see it for myself - as I'm sure others would be too.
