What is the smallest setup you have ever used to cast?
Here is mine:
Micro "Open Jet" Alcohol Burner (Zen Stoves http://zenstoves.net/Stoves.htm) burning Denatured Alcohol (flame invisible under flash)
Lyman Ladle
LEE .690 RB Mould
(all on an aluminium portable drill press plate on my workbench)
Nice way to test the stove... Casting 1oz balls for my Howda.
