The cast aluminum flask pattern created from the 3D printed pattern in the last video is getting some finish work done before its used to create the first cope and drag. After a fair amount of grinding it releases from the sand very nice with no, or at least very minimal crumbling of sand at any of the edges.
I used bolts for alignment pins that I modified on the lathe. This seemed to work good and the main reason for doing so is the price of steel. Small round stock used to be fairly reasonable.
And.... I already found the first small part to cast using this flask. That will be the next video!
