For 20 years, I had a good moonlight job doing stagecraft for live dance theater.
Became very familiar with masks, props and body armour pieces made of thin sheet metal & piano wire.
I believed that they all had to look as good at hand-shaking distance as they would look to the audience.
Scissors, all kinds of thin box card sheet (crisps, crackers, cereals, etc) and a big hot glue gun.
Case of thought provoking beers.
Do some sketchy drawings. Build a full scale model with card and hot glue.
Easy to rip chunks off and splice in new stuff.
Take my cardboard model apart and clone the pieces in metals.
I'd do exactly the same technique if I had to have a stand-alone stove = build the model.
Sheet metal, pop rivet gear ( 1/8" and 9/64" drill bits) clamps and bolts.
Take my cardboard model apart and clone the pieces.
I see many examples here in the BCUK forums where some stamped sheet metal junk has been repurposed
as the basic framework for a stove. I admire those things most of all.
