I made a flask. Man this thing is huge. This will be the largest part I've ever made.
I spent a Sunday ramming it up and pouring. I used a piece of 3/4" plywood attached to the bottom of the drag to prevent sand fallout when moving the flask around.
When I made the flask, I set it up that I could split the two halves with the flasks set on their sides. I knew there was no way I was gonna lift the flask much less lift it straight up. I rammed up the drag and then when I did the cope, I found out that I do not have enough sand The cope and drag are 3.25" thick and I was .75" short of sand for the cope. I worked with it anyway. I had to call up a friend to help me move it. It was way to heavy to do by myself. It probably weighed in the neighborhood of 150 pounds.
I used my largest crucible and when I poured it, no metal came out of the risers. I thought there was no way the part filled. Boy was I surprised when it actually turned out! The metal just started to fill into the runners for the risers. There was just enough.
There are some pitting, but this is a painted part and I will putty up the pits. Also the sand fell out of some of the small letters. I'll have to grind them out by hand. All in all I'm very happy. I love it when a plan comes together.
