Pattern layout
A short video on how to do a pattern layout and a brief talk about shrink rules. Including shrinkage for different alloys.

Thank you for showing the layout process
Do you know if ductile iron shrinks the same as grey iron or no?

Yes, shink is 1/10" to 1/12" per foot. If you know your properties of the ductile iron and need exact measurements. Cast a test bar 1"×1"×12" using a common rule. Then measure the exact amount of shrink. The foundry we dealt with used 1/10" shrink.
