Thanks for the answers
The fume&smell won't be the problem,I know mom would kill me if I aim to rise a casting workshop in the garden,only place here would be the garage ,which is yet occupied by other stuff,so I'll search for an approbiate place to make my casting projects come true(distance between your home and your workshop is sometimes adorable^^).
I remember somebody posted a YT video here from somebody casting steel with an stone coal furnace,didn't find the link yet again.I know the melting temperature of Steel is high ,so it would be a hard task to solve.
That wood&gas burner looks interesting well =)
I've seen some oldschool furnaces in art&bell foundrys ,they looked really interesting to me(will try to find pictures for you).
Thanks ,Julian
