I waited a day for things to harden. I took the molds off of the saw horse and using a utility knife I trimmed any overage on the back of the mold so it would pop off. I followed some advice from YouTube and used compressed air to help separate the surfaces. With a bit of coaxing they both just popped off. Off to the warm boiler room in the house to get really hard so I can make the parts that I really need.
