42890Re: [hobbicast] sheet metal core
- Sep 14, 2013Hello Drag,
Several reasons come to mind.
1)a metal core would crack insulating refractory as it expands while
2)the expansion would warp the sheeting.
3)the warping would crack ITC213 or ITC 100.
4)metal sheeting wouldn't last long where the flame impinges on it.
5)probably lots more but it's bed time.
