If you take a look back at the first photo, the left end went to the top of the casting bucket. With the funnel shape of the two sections, there was no need for extra venting. I have been thinking of using straws where needed. Thin strips of foam sliced off the parent material would be easy to glue onto the main parts.
I had read that it helps to drill down into the foam after the pattern is supported in the sand bucket. This gives the metal a path to follow to start burning down into the foam. Lots of tips on the internet.
