yea that too but it didn't burn thru to the wires
if your sand is falling out it either doesn't have enough bentonite in it or your not ramming it hard enough.
How much bentonite did you add to the sand? 100 pounds of sand needs around 6 to 10 percent clay, also how long have you had the sand mixed.
Tried to pour the same two casting today again, the big one is still all scabby looking, so gonna give it another shot and flip it 180 degrees plus put a core in it to take up some of the space so I don't hve to pour so much metal into the head.
The two small parts I poured short IE ran out of metal, they were the prettiest castings that I've done in Cast Iron in a long time just short about 50 percent.
anyway nice thing was that the iron that I poured was nice and gray and machinable, the house and shed are still in one piece and the dog loves me cause I fixed him a big pork roast for sunday dinner.
