If the crack is bigger than this really thin one in the video, then epoxy will leak through the port to the space behind the facial grey cover to who knows where... That was my experience: 8 tubes went to the ports and I have no idea where. Nothing came through above port. Gravity brought all of it down. I guess crack was bigger than I thought, and bigger than it looked from inside.
Looks like a great product but I wonder how you kept the epoxy from running out the other side of the blocks and did you put carbon fiber on both sides of the block?
Nice demonstration but.. you didn’t use the same block set up with tractor test.. if you notice in the bonding process, the block has a good size chip out of the top right corner.. the block in the pull test doesn’t.. sorry to be that guy..
