This was cast with a length of steel rod embedded in it. I used a smaller length to make up the drag.
Then once I flipped it over, I pulled the short steel piece using a magnet, and replaced it with one that was slightly longer.
This let me locate the second part of the pattern.
I added a fairly large riser between the sprue and the piece, and it did the job, no shrinkage.
It needs a little cleaning up. The circle over the steel pin is not shrinkage, it is smooth and level, but you certainly can see that the metal solidified a little differently there. If I was doing it again, I'd have a shorter pin, so it didn't come as close to the surface.
