Roger asked me to post this so here it is. Pretty much straight forward. Instead of carving 180 sticks for the trim I only had to carve each of the masters and then I can cast the rest as they will be covered in gilt.
Here all that is needed is to make a mold of the master. I did these in silicon instead of rubber.
Once I had the mold i repurposed the form to make the castings. I decided to make
them out of high density foam so I needed a kid because of the expansion factor. Had I cast in resins this would not be necessary of course.
One nice trick with the HDF is a release agent ( using a silicone mold) isn't needed so that is a benefit and if you give the mold a quick shot of primer it will act as a sort of release agent as well as give you a primed ( in all the nooks and crannies) stick of molding.
Here you can see the molds being taken of the masters.
The stencil I made to spray primer into the mold.

The cast popped out of the mold.
and the results of a couple hrs work.
