I cast the face plate.
It was cast on a steel mandrel, which I had to drill out quite a bit before I could drive it out with a hammer and punch.
After a few attempts at molding this, where the pattern lifted the sand in the slots, I tried just pressing 2 panel pins in to each of the slots and that worked.
That gave the slots just enough support to stay in place as I rapped and removed the pattern.
And yes this photo was staged after the event, I was in a hurry to get set up and cast, as the forecast was only good for the morning. The steel mandrel is missing from the pattern here.
I still have a fair bit of work to go before I am ready to machine the face plate.
