Fun with resin

It's a silicone material called "Mold Max 20". Incredibly easy to work with and provides a mold that captures every detail (hence the first Frost and Woods No.36 grenades made since the war). The spoons are aluminium cut and bent to the right curve, the plungers are 5/16" rod with the notch cut with a Dremel tool, and the rings are 1-1/4" inch key rings....harder to find in quantity than I would have thought. The wood core is just to save on resin. I'm a cheapskate.

My only worry with the signal rounds was I cast an unfired one in the silicone mold mix. The mix heats up on curing and I had this uneasy feeling that heat might cook off the round. It turns out the heat was insignificant and I didn't blow up the workshop.
