I want to use 2mm Lantor Soric for building a model boat and I want to place the infusion spiral in the middle of the part. Do I need to cut the Lantor Soric in halves just below the infusion spiral or will the resin flow through it?
On all videos I have seen, the resin starts flowing from the edge, but I am not sure if I can put the spiral on top.

When you get a chance, I'd be interested to know what you changed in your test, Oekmont?

This is my little experiment. Forgive the video quality, my filmography skills aren't up to Mat's level!

Fairly obvious, but to be clear: The stack on the left is with the resin inlet directly on top of the Soric, the one in the middle is with the inlet in front of the Soric, and the stack on the right is with 3D PET core. The 3D PET core stack should have been the same size to be worth noting, but I didn't have any similar sized off-cuts, so really it is only worth looking at to note how it works having flow mesh on the edge of the core just to initiate the resin flow. Another point worth making is that usually I would use a silicone through-bag connector rather than just having the hose through the bagging tape, as this causes bridging around the hose which is why the resin tracked backwards so quickly on the first stack.

Layup is as I mentioned above and is the same for each panel, 450g biaxial fibreglass > core > 450g biaxial fibreglass.
