I sent a message to Vans as well, but figured input from everywhere won't hurt.
I thought that rolling the mid side skins went well, but while deburring them today, it became apparent that it did not go well.
I simply stop-drilled the end of the crack, then removed all the cracked material so that I could properly debur in case cracks started the other way. The last photo is my repair attempt.
Is this okay, or should I replace the skin? I had similar problems with the forward skins and replaced them, but these are going to be more expensive and are probably going to cost a small fortune to ship.
I'm leaning toward going with my repaired skin, but if that's a terrible idea I'll replace it.
I have no idea why Vans couldn't have rolled these skins for us like they did the tail cone skins.
