The two halves of the mold would be clamped together and the syringe attached to a threaded nipple on the mold . . . Of course, there would have to be a small hole to allow air to escape and the resin to completely fill the mold . . . . Once cured, the mold is unclamped and the sides are separated . . . Presto !
Thoughts ?

If you can mix in some fiberglass matting, that might enable making it lighter and also less brittle. I would mold it with the bottom open to facilitate inserting the matting. But some experimentation will be required to find a way to keep the wall reasonably thin.
