cast iron melt - dallen - 08-05-2015
I told PeteO that I would post up a video of how I light my furnace, well here it is.

Impressive! Thanks for posting that video.

impressive as all get out in the backyard when we did it this morning cause it was almost triple digits in the shade with the humidity steadily climbing to catch up with it.
Thanks, it takes forever to take and edit the stupid things, anyway it does me, some of that may be the free software that I'm using not sure about that one thou.
I wish I could get some better down the Exhaust port shots its pure hell inside when its running,

Thanks David

Man I enjoyed watching that! I've been itching for you to post this since I saw you'd been doing some casting in the projects thread. Thanks heaps for taking the time, I know this stuff is very time consuming, I don't have any video software but even just editing still photos takes me ages so i can appreciate that there's a lot of time in getting a video together.
I have some of that ceramic wool left over, it's what I used for the outer insulation in my furnace, might last my lifetime if it keeps getting blown out the top to re-use! I might put it on the end of a wire though, especially in summer here we're bushfire prone.
I didn't quite catch what you said you put under the crucible to stop it sticking to the plinth, did you say a board? I've read to use cardboard for this, seems just about every backyard casting video on youtube they end up pulling the plinth out with the crucible and then wrestling to get the thing off while it's all glowing white hot. Might try and avoid that.
Does your roof extend over the furnace? I've been wondering about firing up the furnace inside my shed, the roof is about 20' high, don't know whether it would be a problem or not. Won't stop raining here at the moment- except when it's hailing. Give it 6 months and it'll be 100 degrees here too.
I was hoping to get my casting flasks made up this week while I have some days off, but a friend has hurt his back and needs a hand with some jobs so maybe next week....

I just happen to use the ceramic fiber to light it with cause there is usually some scrapes laying around, a rag on a wire soaked in oil will do the same thing, and the wire will stop it from being blown out into the grass. We have the same problem of grass fires here, this year not so much cause we received about 2 feet of rain in the Month of May.
I use a thin piece of Ply if I have some laying around something like 6 Mil cut in a rough circle a little bigger then the bottom of the crucible, it works better then paper cause it leaves a thicker layer of charcoal that doesn't burn out because it can't get any oxygen until you open the furnace and pull the crucible.
The furnace sits about half way under the roof, and its only about 5 feet over the top of the furnace. if your roof is 20 feet I would give it a try inside, but remember these things pump out tons of CO and CO2 which can sneek up and put you to sleep for a long time so open all the windows.
Glad you liked the video, I think its just neater then most things to be able to melt something like Cast Iron and make something from it.
I need to go back and look at your burner setup.
